PCRE_JIT_STACK_ALLOC(3)   OpenBSD Programmer's Manual  PCRE_JIT_STACK_ALLOC(3)



NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       pcre_jit_stack *pcre_jit_stack_alloc(int startsize,
            int maxsize);

       pcre16_jit_stack *pcre16_jit_stack_alloc(int startsize,
            int maxsize);

       pcre32_jit_stack *pcre32_jit_stack_alloc(int startsize,
            int maxsize);

DESCRIPTION

       This function is used to create a stack for use by the code compiled by
       the JIT optimization of pcre[16|32]_study(). 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
       pcre[16|32]_assign_jit_stack(), 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 pcrejit
       page.

       There is a complete description of the PCRE native API in the pcreapi
       page and a description of the POSIX API in the pcreposix page.
