SYNOPSIS

#include <pcre.h>

int pcre_get_stringtable_entries(const pcre *code, const char *name, char **first, char **last);

int pcre16_get_stringtable_entries(const pcre16 *code, PCRE_SPTR16 name, PCRE_UCHAR16 **first, PCRE_UCHAR16 **last);

int pcre32_get_stringtable_entries(const pcre32 *code, PCRE_SPTR32 name, PCRE_UCHAR32 **first, PCRE_UCHAR32 **last);

DESCRIPTION

This convenience function finds, for a compiled pattern, the first and last entries for a given name in the table that translates capturing parenthesis names into numbers. When names are required to be unique (PCRE_DUPNAMES is not set), it is usually easier to use pcre[16|32]_get_stringnumber() instead.

 code Compiled regular expression
 name Name whose entries required
 first Where to return a pointer to the first entry
 last Where to return a pointer to the last entry

The yield of the function is the length of each entry, or PCRE_ERROR_NOSUBSTRING if none are found.

There is a complete description of the PCRE native API, including the format of the table entries, in the pcreapi page, and a description of the POSIX API in the pcreposix page.
