.TH PCRE2_JIT_STACK_CREATE 3 "03 November 2014" "PCRE2 10.00" .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. If the "fast path" JIT matcher, \fBpcre2_jit_match()\fP is used, the stack can be passed directly as an argument. A maximum stack size of 512K to 1M 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.
