library that -supports 16-bit character strings, including UTF-16 strings, as well as or -instead of the original 8-bit library. The majority of the work to make this -possible was done by Zoltan Herczeg. The two libraries contain identical sets -of functions, used in exactly the same way. Only the names of the functions and -the data types of their arguments and results are different. To avoid -over-complication and reduce the documentation maintenance load, most of the -PCRE documentation describes the 8-bit library, with only occasional references -to the 16-bit library. This page describes what is different when you use the -16-bit library. -</P> -<P> -WARNING: A single application can be linked with both libraries, but you must -take care when processing any particular pattern to use functions from just one -library. For example, if you want to study a pattern that was compiled with -<b>pcre16_compile()</b>, you must do so with <b>pcre16_study()</b>, not -<b>pcre_study()</b>, and you must free the study data with -<b>pcre16_free_study()</b>. -</P> -<br><a name="SEC7" href="#TOC1">THE HEADER FILE</a><br> -<P> -There is only one header file, <b>pcre.h</b>. It contains prototypes for all the -functions in all libraries, as well as definitions of flags, structures, error -codes, etc. -</P> -<br><a name="SEC8" href="#TOC1">THE LIBRARY NAME</a><br> -<P> -In Unix-like systems, the 16-bit library is called <b>libpcre16</b>, and can -normally be accesss by adding <b>-lpcre16</b> to the command for linking an -application that uses PCRE. -</P> -<br><a name="SEC9" href="#TOC1">STRING TYPES</a><br> -<P> -In the 8-bit library, strings are passed to PCRE library functions as vectors -of bytes with the C type "char *". In the 16-bit library, strings are passed as -vectors of unsigned 16-bit quantities. The macro PCRE_UCHAR16 specifies an -appropriate data type, and PCRE_SPTR16 is defined as "const PCRE_UCHAR16 *". In -very many environments, "short int" is a 16-bit data type. When PCRE is built, -it defines PCRE_UCHAR16 as "unsigned short int", but checks that it really is a -16-bit data type. If it is not, the build fails with an error message telling -the maintainer to modify the definition appropriately. -</P> -<br><a name="SEC10" href="#TOC1">STRUCTURE TYPES</a><br> -<P> -The types of the opaque structures that are used for compiled 16-bit patterns -and JIT stacks are <b>pcre16</b> and <b>pcre16_jit_stack</b> respectively. The -type of the user-accessible structure that is returned by <b>pcre16_study()</b> -is <b>pcre16_extra</b>, and the type of the structure that is used for passing -data to a callout function is <b>pcre16_callout_block</b>. These structures -contain the same fields, with the same names, as their 8-bit counterparts. The -only difference is that pointers to character strings are 16-bit instead of -8-bit types. -</P> -<br><a name="SEC11" href="#TOC1">16-BIT FUNCTIONS</a><br> -<P> -For every function in the 8-bit library there is a corresponding function in -the 16-bit library with a name that starts with <b>pcre16_</b> instead of -<b>pcre_</b>. The prototypes are listed above. In addition, there is one extra -function, <b>pcre16_utf16_to_host_byte_order()</b>. This is a utility function -that converts a UTF-16 character string to host byte order if necessary. The -other 16-bit functions expect the strings they are passed to be in host byte -order. -</P> -<P> -The <i>input</i> and <i>output</i> arguments of -<b>pcre16_utf16_to_host_byte_order()</b> may point to the same address, that is, -conversion in place is supported. The output buffer must be at least as long as -the input. -</P> -<P> -The <i>length</i> argument specifies the number of 16-bit data units in the -input string; a negative value specifies a zero-terminated string. -</P> -<P> -If <i>byte_order</i> is NULL, it is assumed that the string starts off in host -byte order. This may be changed by byte-order marks (BOMs) anywhere in the -string (commonly as the first character). -</P> -<P> -If <i>byte_order</i> is not NULL, a non-zero value of the integer to which it -points means that the input starts off in host byte order, otherwise the -opposite order is assumed. Again, BOMs in the string can change this. The final -byte order is passed back at the end of processing. -</P> -<P> -If <i>keep_boms</i> is not zero, byte-order mark characters (0xfeff) are copied -into the output string. Otherwise they are discarded. -</P> -<P> -The result of the function is the number of 16-bit units placed into the output -buffer, including the zero terminator if the string was zero-terminated. -</P> -<br><a name="SEC12" href="#TOC1">SUBJECT STRING OFFSETS</a><br> -<P> -The lengths and starting offsets of subject strings must be specified in 16-bit -data units, and the offsets within subject strings that are returned by the -matching functions are in also 16-bit units rather than bytes. -</P> -<br><a name="SEC13" href="#TOC1">NAMED SUBPATTERNS</a><br> -<P> -The name-to-number translation table that is maintained for named subpatterns -uses 16-bit characters. The <b>pcre16_get_stringtable_entries()</b> function -returns the length of each entry in the table as the number of 16-bit data -units. -</P> -<br><a name="SEC14" href="#TOC1">OPTION NAMES</a><br> -<P> -There are two new general option names, PCRE_UTF16 and PCRE_NO_UTF16_CHECK, -which correspond to PCRE_UTF8 and PCRE_NO_UTF8_CHECK in the 8-bit library. In -fact, these new options define the same bits in the options word. There is a -discussion about the -<a href="pcreunicode.html#utf16strings">validity of UTF-16 strings</a> -in the -<a href="pcreunicode.html"><b>pcreunicode</b></a> -page. -</P> -<P> -For the <b>pcre16_config()</b> function there is an option PCRE_CONFIG_UTF16 -that returns 1 if UTF-16 support is configured, otherwise 0. If this option is -given to <b>pcre_config()</b> or <b>pcre32_config()</b>, or if the -PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF32 option is given to <b>pcre16_config()</b>, -the result is the PCRE_ERROR_BADOPTION error. -</P> -<br><a name="SEC15" href="#TOC1">CHARACTER CODES</a><br> -<P> -In 16-bit mode, when PCRE_UTF16 is not set, character values are treated in the -same way as in 8-bit, non UTF-8 mode, except, of course, that they can range -from 0 to 0xffff instead of 0 to 0xff. Character types for characters less than -0xff can therefore be influenced by the locale in the same way as before. -Characters greater than 0xff have only one case, and no "type" (such as letter -or digit). -</P> -<P> -In UTF-16 mode, the character code is Unicode, in the range 0 to 0x10ffff, with -the exception of values in the range 0xd800 to 0xdfff because those are -"surrogate" values that are used in pairs to encode values greater than 0xffff. -</P> -<P> -A UTF-16 string can indicate its endianness by special code knows as a -byte-order mark (BOM). The PCRE functions do not handle this, expecting strings -to be in host byte order. A utility function called -<b>pcre16_utf16_to_host_byte_order()</b> is provided to help with this (see -above). -</P> -<br><a name="SEC16" href="#TOC1">ERROR NAMES</a><br> -<P> -The errors PCRE_ERROR_BADUTF16_OFFSET and PCRE_ERROR_SHORTUTF16 correspond to -their 8-bit counterparts. The error PCRE_ERROR_BADMODE is given when a compiled -pattern is passed to a function that processes patterns in the other -mode, for example, if a pattern compiled with <b>pcre_compile()</b> is passed to -<b>pcre16_exec()</b>. -</P> -<P> -There are new error codes whose names begin with PCRE_UTF16_ERR for invalid -UTF-16 strings, corresponding to the PCRE_UTF8_ERR codes for UTF-8 strings that -are described in the section entitled -<a href="pcreapi.html#badutf8reasons">"Reason codes for invalid UTF-8 strings"</a> -in the main -<a href="pcreapi.html"><b>pcreapi</b></a> -page. The UTF-16 errors are: -<pre> - PCRE_UTF16_ERR1 Missing low surrogate at end of string - PCRE_UTF16_ERR2 Invalid low surrogate follows high surrogate - PCRE_UTF16_ERR3 Isolated low surrogate - PCRE_UTF16_ERR4 Non-character -</PRE> -</P> -<br><a name="SEC17" href="#TOC1">ERROR TEXTS</a><br> -<P> -If there is an error while compiling a pattern, the error text that is passed -back by <b>pcre16_compile()</b> or <b>pcre16_compile2()</b> is still an 8-bit -character string, zero-terminated. -</P> -<br><a name="SEC18" href="#TOC1">CALLOUTS</a><br> -<P> -The <i>subject</i> and <i>mark</i> fields in the callout block that is passed to -a callout function point to 16-bit vectors. -</P> -<br><a name="SEC19" href="#TOC1">TESTING</a><br> -<P> -The <b>pcretest</b> program continues to operate with 8-bit input and output -files, but it can be used for testing the 16-bit library. If it is run with the -command line option <b>-16</b>, patterns and subject strings are converted from -8-bit to 16-bit before being passed to PCRE, and the 16-bit library functions -are used instead of the 8-bit ones. Returned 16-bit strings are converted to -8-bit for output. If both the 8-bit and the 32-bit libraries were not compiled, -<b>pcretest</b> defaults to 16-bit and the <b>-16</b> option is ignored. -</P> -<P> -When PCRE is being built, the <b>RunTest</b> script that is called by "make -check" uses the <b>pcretest</b> <b>-C</b> option to discover which of the 8-bit, -16-bit and 32-bit libraries has been built, and runs the tests appropriately. -</P> -<br><a name="SEC20" href="#TOC1">NOT SUPPORTED IN 16-BIT MODE</a><br> -<P> -Not all the features of the 8-bit library are available with the 16-bit -library.
