NAME        top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS        top

#include <pcre2.h>const uint8_t *pcre2_maketables(pcre2_general_context *gcontext);

DESCRIPTION        top

       This function builds a set of character tables for character code       points that are less than 256. These can be passed topcre2_compile()in a compile context in order to override the       internal, built-in tables (which were either defaulted or made bypcre2_maketables()when PCRE2 was compiled). See thepcre2_set_character_tables()page. You might want to do this if       you are using a non-standard locale.       If the argument is NULL,malloc()is used to get memory for the       tables.  Otherwise it must point to a general context, which can       supply pointers to a custom memory manager. The function yields a       pointer to the tables.       There is a complete description of the PCRE2 native API in thepcre2apipage and a description of the POSIX API in thepcre2posix       page.
