PCRE2_SET_MAX_PATTERN_LENGTH(3) Library Functions Manual NAME PCRE2 - Perl-compatible regular expressions (revised API) SYNOPSIS #include int pcre2_set_max_pattern_length(pcre2_compile_context *ccontext, PCRE2_SIZE value); 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. 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. PCRE2 10.23 05 October 2016 PCRE2_SET_MAX_PATTERN_LENGTH(3)
