fnmatch
— test
whether a filename or pathname matches a shell-style pattern
Standard C Library (libc, -lc)

fnmatch
(const
char *pattern, const char
*string, int
flags);
The
fnmatch
()
function matches patterns according to the 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
\
’) followed by a character in
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.FNM_PATHNAME
FNM_PERIOD
FNM_PATHNAME
. A period is always
“leading” if it is the first character in
string. Additionally, if
FNM_PATHNAME
is set, a period is leading if it
immediately follows a slash.FNM_LEADING_DIR
/*
” rest after successful
pattern matching.FNM_CASEFOLD
The fnmatch
() function returns zero if
string matches the pattern specified by
pattern. It returns the value
FNM_NOMATCH
if no match is found. Otherwise, another
non-zero value is returned on error.
The
fnmatch
()
function returns zero if string matches the pattern
specified by pattern; otherwise, it returns the value
FNM_NOMATCH
.
The current implementation of the
fnmatch
() function
does not
conform to IEEE Std 1003.2
(“POSIX.2”). Collating symbol expressions, equivalence
class expressions and character class expressions are not supported.
The fnmatch
() function first appeared in
4.4BSD.
The pattern ‘*
’ matches the
empty string, even if FNM_PATHNAME
is specified.
