PCRE — Perl-compatible regular expressions


#include <pcre.h>
int pcre_get_stringnumber( const pcre *code,
  const char *name);
int pcre16_get_stringnumber( const pcre16 *code,
  PCRE_SPTR16 name);
int pcre32_get_stringnumber( const pcre32 *code,
  PCRE_SPTR32 name);


This convenience function finds the number of a named substring capturing parenthesis in a compiled pattern. Its arguments are:

 code    Compiled regular expression
 name    Name whose number is required

The yield of the function is the number of the parenthesis if the name is found, or PCRE_ERROR_NOSUBSTRING otherwise. When duplicate names are allowed (PCRE_DUPNAMES is set), it is not defined which of the numbers is returned by pcre[16|32]_get_stringnumber(). You can obtain the complete list by calling pcre[16|32]_get_stringtable_entries().

There is a complete description of the PCRE native API in the pcreapi(3) page and a description of the POSIX API in the pcreposix(3) page.
