.SH "RETURN VALUE
If successful, the

.SH "ERRORS
.B Read
+and
+.B pread
will fail if one or more of the following are true:
.TP 15
[EBADF]
[EAGAIN]
The file was marked for non-blocking I/O,
and no data were ready to be read.

+.TH FNMATCH 3 "July 18, 2004"
+.AT 3
+.SH NAME
+fnmatch \- test whether a filename or pathname matches a shell-style pattern
+.SH SYNOPSIS
+.nf
+.ft B
+#include <fnmatch.h>
+
+int fnmatch(const char *\fIpattern\fP, const char *\fIstring\fP, int \fIflags\fP);
+.ft R
+.fi
+.SH DESCRIPTION
+The
+.B fnmatch
+function matches patterns according to the rules used by the shell.
+It checks the string specified by the
+.IR string
+argument to see if it matches the pattern specified by the
+.IR pattern
+argument.
+.PP
+The
+.IR flags
+argument modifies the interpretation of
+.IR pattern
+and
+.IR string .
+The value of
+.IR flags
+is the bitwise inclusive OR of any of the following
+constants, which are defined in the include file fnmatch.h.
+.TP 15
+FNM_NOESCAPE
+Normally, every occurrence of a backslash followed by a character in
+.IR pattern
+is replaced by that character.
+This is done to negate any special meaning for the character.
+If the FNM_NOESCAPE
+flag is set, a backslash character is treated as an ordinary character.
+.TP 15
+FNM_PATHNAME
+Slash characters in
+.IR string
+must be explicitly matched by slashes in
+.IR pattern .
+If this flag is not set, then slashes are treated as regular characters.
+.TP 15
+FNM_PERIOD
+Leading periods in
+.IR string
+must be explicitly matched by periods in
+.IR pattern .
+If this flag is not set, then leading periods are treated as regular
+characters.
+The definition of leading is related to the specification of FNM_PATHNAME.
+A period is always leading if it is the first character in
+.IR string .
+Additionally, if FNM_PATHNAME is set, a period is leading
+if it immediately follows a slash.
+.TP 15
+FNM_LEADING_DIR
+Ignore /* rest after successful
+.IR pattern
+matching.
+.TP 15
+FNM_CASEFOLD
+Ignore case distinctions in both the
+.IR pattern
+and the
+.IR string .
+.SH RETURN VALUES
+The
+.B fnmatch
+function returns zero if
+.IR string
+matches the pattern specified by
+.IR pattern ,
+otherwise, it returns the value FNM_NOMATCH.
+.SH SEE ALSO
+.BR sh (1),
+.BR regex (3),
+.SH HISTORY
+The
+.B fnmatch
+function first appeared in 4.4BSD.
+.SH BUGS
+The pattern * matches the empty string, even if FNM_PATHNAME is specified.
