NAME        top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS        top

#include <pcre2.h>pcre2_match_data *pcre2_match_data_create(uint32_tovecsize,pcre2_general_context *gcontext);

DESCRIPTION        top

       This function creates a new match data block, which is used for       holding the result of a match. The first argument specifies the       number of pairs of offsets that are required. These form the       "output vector" (ovector) within the match data block, and are       used to identify the matched string and any captured substrings       when matching withpcre2_match(), or a number of different matches       at the same point when used withpcre2_dfa_match(). There is       always one pair of offsets; ifovecsizeis zero, it is treated as       one.       The second argument points to a general context, for custom memory       management, or is NULL for system memory management. The result of       the function is NULL if the memory for the block could not be       obtained.       There is a complete description of the PCRE2 native API in thepcre2apipage and a description of the POSIX API in thepcre2posix       page.
