+.TH FNMATCH 3am "Jan 15 2013" "Free Software Foundation" "GNU Awk Extension Modules"
+.SH NAME
+fnmatch \- compare a string against a filename wildcard
+.SH SYNOPSIS
+.ft CW
+@load "fnmatch"
+.sp
+result = fnmatch(pattern, string, flags)
+.ft R
+.SH DESCRIPTION
+The
+.I fnmatch
+extension provides an AWK interface to the
+.IR fnmatch (3)
+routine.  It adds a single function named
+.BR fnmatch() ,
+one predefined variable
+.RB ( FNM_NOMATCH ),
+and an array of flag values named
+.BR FNM .
+.PP
+The first argument is the filename wildcard to match, the second
+is the filename string, and the third is either zero,
+or the bitwise OR of one or more of the flags in the
+.B FNM
+array.
+.PP
+The return value is zero on success,
+.B FNM_NOMATCH
+if the string did not match the pattern, or
+a different non-zero value if an error occurred.
+.PP
+The flags are follows:
+.TP
+\fBFNM["CASEFOLD"]\fP
+Corresponds to the
+.B FNM_CASEFOLD
+flag as defined in
+.IR fnmatch (3).
+.TP
+\fBFNM["FILE_NAME"]\fP
+Corresponds to the
+.B FNM_FILE_NAME
+flag as defined in
+.IR fnmatch (3).
+.TP
+\fBFNM["LEADING_DIR"]\fP
+Corresponds to the
+.B FNM_LEADING_DIR
+flag as defined in
+.IR fnmatch (3).
+.TP
+\fBFNM["NOESCAPE"]\fP
+Corresponds to the
+.B FNM_NOESCAPE
+flag as defined in
+.IR fnmatch (3).
+.TP
+\fBFNM["PATHNAME"]\fP
+Corresponds to the
+.B FNM_PATHNAME
+flag as defined in
+.IR fnmatch (3).
+.TP
+\fBFNM["PERIOD"]\fP
+Corresponds to the
+.B FNM_PERIOD
+flag as defined in
+.IR fnmatch (3).
+.PP
+.SH NOTES
+Nothing prevents AWK code from changing the predefined
+variabale
+.BR FNM_NOMATCH ,
+but doing so may cause strange results.
+... .SH BUGS
+.SH EXAMPLE
