NAME
fnmatch —
match filename or pathname using shell
glob rules
LIBRARY
library “libc”
SYNOPSIS
#include
<fnmatch.h>
int
fnmatch(const
char *pattern, const char
*string, int
flags);
DESCRIPTION
Thefnmatch()
function matches patterns according to the globbing rules used by the shell.
It checks the string specified by the string argument to
see if it matches the pattern specified by the pattern
argument.
The flags argument modifies the interpretation of pattern and string. The value of flags is the bitwise inclusive OR of any of the following constants, which are defined in the include file fnmatch.h.
FNM_NOESCAPE- Normally, every occurrence of a backslash
(‘
\’) followed by a character in pattern is replaced by that character. This is done to negate any special meaning for the character. If theFNM_NOESCAPEflag is set, a backslash character is treated as an ordinary character. FNM_PATHNAME- Slash characters in string must be explicitly matched by slashes in pattern. If this flag is not set, then slashes are treated as regular characters.
FNM_PERIOD- Leading periods in strings match periods in patterns. The definition of
``leading'' is related to the specification of
FNM_PATHNAME. A period is always ``leading'' if it is the first character in string. Additionally, ifFNM_PATHNAMEis set, a period is ``leading'' if it immediately follows a slash. FNM_LEADING_DIR- Ignore “/*” rest after successful pattern matching.
FNM_CASEFOLD- The pattern is matched in a case-insensitive fashion.
RETURN VALUES
The fnmatch() function returns zero if
string matches the pattern specified by
pattern, otherwise, it returns the value
FNM_NOMATCH.
SEE ALSO
STANDARDS
The fnmatch() function conforms to
IEEE Std 1003.2-1992 (“POSIX.2”). The
FNM_CASEFOLD flag is a
NetBSD extension.
HISTORY
The fnmatch() function first appeared in
4.4BSD.
BUGS
The pattern ‘*’ matches the
empty string, even if FNM_PATHNAME is specified.
