NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
int pcre2_set_optimize(pcre2_compile_context *ccontext, uint32_t directive);
DESCRIPTION
This function controls which performance optimizations will be applied by pcre2_compile(). It can be called multiple times with the same compile context; the effects are cumulative, with the effects of later calls taking precedence over earlier ones.
The result is zero for success, PCRE2_ERROR_NULL if ccontext is NULL, or PCRE2_ERROR_BADOPTION if directive is unknown. The latter could be useful to detect if a certain optimization is available.
The list of possible values for the directive parameter are:
PCRE2_OPTIMIZATION_FULL Enable all optimizations (default)
PCRE2_OPTIMIZATION_NONE Disable all optimizations
PCRE2_AUTO_POSSESS Enable auto-possessification
PCRE2_AUTO_POSSESS_OFF Disable auto-possessification
PCRE2_DOTSTAR_ANCHOR Enable implicit dotstar anchoring
PCRE2_DOTSTAR_ANCHOR_OFF Disable implicit dotstar anchoring
PCRE2_START_OPTIMIZE Enable start-up optimizations at match time
PCRE2_START_OPTIMIZE_OFF Disable start-up optimizations at match time
There is a complete description of the PCRE2 native API, including detailed descriptions directive parameter values in the pcre2api page.
