Manual page for PCRE2 10.50-DEV

Name

pcre2_set_max_pattern_length - set the maximum length of a pattern

Synopsis

#include <pcre2.h>

int pcre2_set_max_pattern_length(pcre2_compile_context *ccontext,
                                 PCRE2_SIZE length);

Description

This function sets, in a compile context, the maximum text length (in code units) of the pattern that can be compiled. The result is always zero. If a longer pattern is passed to pcre2_compile() there is an immediate error return. The default is effectively unlimited, being the largest value a PCRE2_SIZE variable can hold. Setting this value makes the limit unlimited.

There is a complete description of the PCRE2 native API in the pcre2api page and a description of the POSIX API in the pcre2posix page.
