The arguments are: +.sp + extra the data pointer returned by \fBpcre[16|32]_study()\fP + callback a callback function + data a JIT stack or a value to be passed to the callback + function +.P +If \fIcallback\fP is NULL and \fIdata\fP is NULL, an internal 32K block on +the machine stack is used. +.P +If \fIcallback\fP is NULL and \fIdata\fP is not NULL, \fIdata\fP must +be a valid JIT stack, the result of calling \fBpcre[16|32]_jit_stack_alloc()\fP. +.P +If \fIcallback\fP not NULL, it is called with \fIdata\fP as an argument at +the start of matching, in order to set up a JIT stack. If the result is NULL, +the internal 32K stack is used; otherwise the return value must be a valid JIT +stack, the result of calling \fBpcre[16|32]_jit_stack_alloc()\fP. +.P +You may safely assign the same JIT stack to multiple patterns, as long as they +are all matched in the same thread. In a multithread application, each thread +must use its own JIT stack.
