Library Functions Manual PCRE2_SUBSTRING_LENGTH_BYNUMBER(3) NAME PCRE2 - Perl-compatible regular expressions (revised API) SYNOPSIS #include <pcre2.h> int pcre2_substring_length_bynumber(pcre2_match_data *match_data, uint32_t number, PCRE2_SIZE *length); DESCRIPTION This function returns the length of a matched substring, identified by number. The arguments are: match_data The match data block for the match number The substring number length Where to return the length, or NULL The third argument may be NULL if all you want to know is whether or not a substring is set. The yield is zero on success, or a negative error code otherwise. After a partial match, only substring 0 is avail- able.
