.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
