| SYNOPSIS |
| </h2> |
| <p> |
| <b>#include <pcre2.h></b> |
| </p> |
| <p> |
| <b>int pcre2_set_optimize(pcre2_compile_context *<i>ccontext</i>,</b> |
| <b> uint32_t <i>directive</i>);</b> |
| </p> |
| <h2> |
| DESCRIPTION |
| </h2> |
| <p> |
| This function controls which performance optimizations will be applied |
| by <b>pcre2_compile()</b>. 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. |
| </p> |
| <p> |
| The result is zero for success, PCRE2_ERROR_NULL if <i>ccontext</i> is NULL, |
| or PCRE2_ERROR_BADOPTION if <i>directive</i> is unknown. The latter could be |
| useful to detect if a certain optimization is available. |
| </p> |
| <p> |
| The list of possible values for the <i>directive</i> parameter are: |
| <pre> |
| 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 |
| </pre> |
| There is a complete description of the PCRE2 native API, including detailed |
| descriptions <i>directive</i> parameter values in the |
| <a href="pcre2api.html"><b>pcre2api</b></a> |
| page. |
