- .TH PCRE2_JIT_STACK_CREATE 3 "24 March 2017" "PCRE2 10.30"
- .SH NAME
- PCRE2 - Perl-compatible regular expressions (revised API)
- .SH SYNOPSIS
- .rs
- .sp
- .B #include <pcre2.h>
- .PP
- .nf
- .B pcre2_jit_stack *pcre2_jit_stack_create(PCRE2_SIZE \fIstartsize\fP,
- .B " PCRE2_SIZE \fImaxsize\fP, pcre2_general_context *\fIgcontext\fP);"
- .fi
- .
- .SH DESCRIPTION
- .rs
- .sp
- This function is used to create a stack for use by the code compiled by the JIT
- compiler. The first two arguments are a starting size for the stack, and a
- maximum size to which it is allowed to grow. The final argument is a general
- context, for memory allocation functions, or NULL for standard memory
- allocation. The result can be passed to the JIT run-time code by calling
- \fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern,
- which can then be processed by \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP.
- A maximum stack size of 512KiB to 1MiB should be more than enough for any
- pattern. For more details, see the
- .\" HREF
- \fBpcre2jit\fP
- .\"
- page.
- .P
- There is a complete description of the PCRE2 native API in the
- .\" HREF
- \fBpcre2api\fP
- .\"
- page and a description of the POSIX API in the
- .\" HREF
- \fBpcre2posix\fP
- .\"
- page.
