+.SH DESCRIPTION
+.rs
+.sp
+This function is used to create a stack for use by the code compiled by the JIT
+optimization of \fBpcre[16|32]_study()\fP. The arguments are a starting size for
+the stack, and a maximum size to which it is allowed to grow. The result can be
+passed to the JIT run-time code by \fBpcre[16|32]_assign_jit_stack()\fP, or that
+function can set up a callback for obtaining a stack. A maximum stack size of
+512K to 1M should be more than enough for any pattern. For more details, see
+the
+.\" HREF
+\fBpcrejit\fP
+.\"
+page.
+.P
+There is a complete description of the PCRE native API in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+page and a description of the POSIX API in the
+.\" HREF
+\fBpcreposix\fP
+.\"
