+.TH PCRE_GET_NAMED_SUBSTRING 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH SYNOPSIS
+.rs
+.sp
+.B #include <pcre.h>
+.PP
+.SM
+.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);
+.
+.SH DESCRIPTION
+.rs
+.sp
+This is a convenience function for extracting a captured substring by name. The
+arguments are:
+.sp
+ \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
+.sp
+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.
+.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.
