| .TH PCRE2_MATCH_DATA_CREATE 3 "28 August 2021" "PCRE2 10.38" | |
| .SH NAME | |
| PCRE2 - Perl-compatible regular expressions (revised API) | |
| .SH SYNOPSIS | |
| .rs | |
| .sp | |
| .B #include <pcre2.h> | |
| .PP | |
| .nf | |
| .B pcre2_match_data *pcre2_match_data_create(uint32_t \fIovecsize\fP, | |
| .B " pcre2_general_context *\fIgcontext\fP);" | |
| .fi | |
| . | |
| .SH DESCRIPTION | |
| .rs | |
| .sp | |
| 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 with \fBpcre2_match()\fP, or a number of different | |
| matches at the same point when used with \fBpcre2_dfa_match()\fP. There is | |
| always one pair of offsets; if \fBovecsize\fP is zero, it is treated as one. | |
| .P | |
| 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. | |
| .P | |
