This is a convenience function for extracting a captured substring by name. The arguments are:
code Compiled pattern subject Subject that has been successfully matched ovector Offset vector thatpcre[16]_exec() used stringcount Value returned bypcre[16]_exec() stringname Name of the required substring stringptr Where to put the string pointer
The memory in which the substring is placed is obtained by
calling pcre[16]_malloc(). The
convenience function pcre[16]_free_substring() can be used to
free it when it is no longer needed. The yield of the
function is the length of the extracted substring,
PCRE_ERROR_NOMEMORY if sufficient memory could not be
obtained, or PCRE_ERROR_NOSUBSTRING if the string name is
invalid.
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.
