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 to
       pcre2_compile() in a compile context in order to override the
       internal, built-in tables (which were either defaulted or made by
       pcre2_maketables() when PCRE2 was compiled). See the
       pcre2_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 the
       pcre2api page and a description of the POSIX API in the pcre2posix
       page.
