Описание (Description)
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 page and a description of the POSIX API in the pcreposix
page.
