PCRE - Perl-compatible regular expressions .rs #include <pcre.h>

const unsigned char *pcre_maketables(void); .

.rs This function builds a set of character tables for character values less than 256. These can be passed to pcre_compile() to override PCRE's internal, built-in tables (which were made by pcre_maketables() when PCRE was compiled). You might want to do this if you are using a non-standard locale. The function yields a pointer to the tables.
