PCRE_ASSIGN_JIT_STACK(3) Library Functions Manual PCRE_ASSIGN_JIT_STACK(3) NAME PCRE - Perl-compatible regular expressions SYNOPSIS #include <pcre.h> void pcre_assign_jit_stack(pcre_extra *extra, pcre_jit_callback callback, void *data); void pcre16_assign_jit_stack(pcre16_extra *extra, pcre16_jit_callback callback, void *data); void pcre32_assign_jit_stack(pcre32_extra *extra, pcre32_jit_callback callback, void *data); DESCRIPTION This function provides control over the memory used as a stack at run- time by a call to pcre[16|32]_exec() with a pattern that has been suc- cessfully compiled with JIT optimization. The arguments are: extra the data pointer returned by pcre[16|32]_study() callback a callback function data a JIT stack or a value to be passed to the callback function If callback is NULL and data is NULL, an internal 32K block on the ma- chine stack is used. If callback is NULL and data is not NULL, data must be a valid JIT stack, the result of calling pcre[16|32]_jit_stack_alloc(). If callback not NULL, it is called with data as an argument at the start of matching, in order to set up a JIT stack. If the result is NULL, the internal 32K stack is used; otherwise the return value must be a valid JIT stack, the result of calling pcre[16|32]_jit_stack_al- loc(). You may safely assign the same JIT stack to multiple patterns, as long as they are all matched in the same thread. In a multithread applica- tion, each thread must use its own JIT stack. 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.
