.TH PCRE_JIT_STACK_ALLOC 3 "24 June 2012" "PCRE 8.30" .SH NAME PCRE - Perl-compatible regular expressions .SH SYNOPSIS .rs .sp .B #include <pcre.h> .PP .nf .B pcre_jit_stack *pcre_jit_stack_alloc(int \fIstartsize\fP, .B " int \fImaxsize\fP);" .sp .B pcre16_jit_stack *pcre16_jit_stack_alloc(int \fIstartsize\fP, .B " int \fImaxsize\fP);" .sp .B pcre32_jit_stack *pcre32_jit_stack_alloc(int \fIstartsize\fP, .B " int \fImaxsize\fP);" .fi . .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 .\" page.
