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(3) page, and a description of the POSIX API in the pcreposix(3) page.
