const char ** | stringptr) ; |
This is a convenience function for extracting a captured substring. The arguments are:
subject
Subject that has been successfully matchedovector
Offset vector thatpcre_exec()
usedstringcount
Value returned bypcre_exec()
stringnumber
Number of the required substringstringptr
Where to put the string pointer
The memory in which the substring is placed is obtained by
calling pcre_malloc()
. The
convenience function pcre_free_substring()
can be
used to free it when it is no longer needed. The yield of the
function is the length of the substring, PCRE_ERROR_NOMEMORY
if sufficient memory could not be obtained, or
PCRE_ERROR_NOSUBSTRING if the string number is invalid.
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.
