+.TH PCRE_GET_STRINGNUMBER 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH SYNOPSIS
+.rs
+.sp
+.B #include <pcre.h>
+.PP
+.SM
+.br
+.B int pcre_get_stringtable_entries(const pcre *\fIcode\fP,
+.ti +5n
+.B const char *\fIname\fP, char **\fIfirst\fP, char **\fIlast\fP);
+.
+.SH DESCRIPTION
+.rs
+.sp
+This convenience function finds, for a compiled pattern, the first and last
+entries for a given name in the table that translates capturing parenthesis
+names into numbers. When names are required to be unique (PCRE_DUPNAMES is
+\fInot\fP set), it is usually easier to use \fBpcre_get_stringnumber()\fP
+instead.
+.sp
+  \fIcode\fP    Compiled regular expression
+  \fIname\fP    Name whose entries required
+  \fIfirst\fP   Where to return a pointer to the first entry
+  \fIlast\fP    Where to return a pointer to the last entry
+.sp
+The yield of the function is the length of each entry, or
+PCRE_ERROR_NOSUBSTRING if none are found.
+.P
+There is a complete description of the PCRE native API, including the format of
+the table entries, in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+page and a description of the POSIX API in the
+.\" HREF
+\fBpcreposix\fP
+.\"
+page.
