The +arguments are: +.sp + \fIsubject\fP Subject that has been successfully matched + \fIovector\fP Offset vector that \fBpcre[16]_exec()\fP used + \fIstringcount\fP Value returned by \fBpcre[16]_exec()\fP + \fIstringnumber\fP Number of the required substring + \fIstringptr\fP Where to put the string pointer +.sp +The memory in which the substring is placed is obtained by calling +\fBpcre[16]_malloc()\fP. The convenience function +\fBpcre[16]_free_substring()\fP 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. +.P +There is a complete description of the PCRE native API in the +.\" HREF +\fBpcreapi\fP +.\" +page and a description of the POSIX API in the +.\" HREF +\fBpcreposix\fP +.\" +page. |
