PCRE2_MATCH_DATA_CREATE_FROLibraryRFuncPCRE2_MATCH_DATA_CREATE_FROM_PATTERN(3)

NAME
       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include	<pcre2.h>

       pcre2_match_data	*pcre2_match_data_create_from_pattern(
	 const pcre2_code *code, pcre2_general_context *gcontext);

DESCRIPTION

       This function creates a new match data block, which is used for holding
       the result of a match. The first	argument points	to a compiled pattern.
       The  number of capturing	parentheses within the pattern is used to com-
       pute the	number of pairs	of offsets that	are required in	the match data
       block.  These  form the "output vector" (ovector) within	the match data
       block, and are used to identify the matched  string  and	 any  captured
       substrings.

       The second argument points to a general context,	for custom memory man-
       agement,	or is NULL to use the same memory allocator as	was  used  for
       the  compiled pattern. 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 the pcre2api
       page and	a description of the POSIX API in the pcre2posix page.
