.TH PCRE2_MAKETABLES 3 "17 April 2017" "PCRE2 10.30"
.SH NAME
PCRE2 - Perl-compatible regular expressions (revised API)
.SH SYNOPSIS
.rs
.sp
.B #include <pcre2.h>
.PP
.SM
.B const uint8_t *pcre2_maketables(pcre2_general_context *\fIgcontext\fP);
.
.SH DESCRIPTION
.rs
.sp
This function builds a set of character tables for character code points that
are less than 256. These can be passed to \fBpcre2_compile()\fP in a compile
context in order to override the internal, built-in tables (which were either
defaulted or made by \fBpcre2_maketables()\fP when PCRE2 was compiled). See the
.\" HREF
\fBpcre2_set_character_tables()\fP
.\"
page. You might want to do this if you are using a non-standard locale.
.P
If the argument is NULL, \fBmalloc()\fP 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.
.P
There is a complete description of the PCRE2 native API in the
.\" HREF
\fBpcre2api\fP
.\"
page and a description of the POSIX API in the
.\" HREF
\fBpcre2posix\fP
.\"
page.
