pcre_get_named_substring.3   [plain text]

PCRE - Perl-compatible regular expressions
.B #include <pcre.h>
.B int pcre_get_named_substring(const pcre *\fIcode\fP,
.ti +5n
.B const char *\fIsubject\fP, int *\fIovector\fP,
.ti +5n
.B int \fIstringcount\fP, const char *\fIstringname\fP,
.ti +5n
.B const char **\fIstringptr\fP);
This is a convenience function for extracting a captured substring by name. The
arguments are:
  \fIcode\fP          Compiled pattern
  \fIsubject\fP       Subject that has been successfully matched
  \fIovector\fP       Offset vector that \fBpcre_exec()\fP used
  \fIstringcount\fP   Value returned by \fBpcre_exec()\fP
  \fIstringname\fP    Name of the required substring
  \fIstringptr\fP     Where to put the string pointer
The memory in which the substring is placed is obtained by calling
\fBpcre_malloc()\fP. The convenience function \fBpcre_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 extracted substring, PCRE_ERROR_NOMEMORY if sufficient memory
could not be obtained, or PCRE_ERROR_NOSUBSTRING if the string name is invalid.
