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