#include <fnmatch.h>int fnmatch(const char *pattern, const char *string, int flags);
DESCRIPTION
The
fnmatch()
function checks whether the
string
argument matches the
pattern
argument, which is a shell wildcard pattern.
The
flags
argument modifies the behaviour; it is the bitwise OR of zero or more
of the following flags:
FNM_NOESCAPE
If this flag is set, treat backslash as an ordinary character,
instead of an escape character.
FNM_PATHNAME
If this flag is set, match a slash in
string
only with a slash in
pattern
and not, for example, with a [] - sequence containing a slash.
FNM_PERIOD
If this flag is set, a leading period in
string
has to be matched exactly by a period in
pattern.
A period is considered to be leading if it is the first character in
string,
or if both
FNM_PATHNAME
is set and the period immediately follows a slash.
FNM_FILE_NAME
This is a GNU synonym for FNM_PATHNAME.
FNM_LEADING_DIR
If this flag (a GNU extension) is set, the pattern is considered to be
matched if it matches an initial segment of
string
which is followed by a slash. This flag is mainly for the internal
use of glibc and is only implemented in certain cases.
FNM_CASEFOLD
If this flag (a GNU extension) is set, the pattern is matched
case-insensitively.
RETURN VALUE
Zero if
string
matches
pattern,
FNM_NOMATCH
if there is no match or another non-zero value if there is an error.
CONFORMING TO
ISO/IEC 9945-2: 1993 (POSIX.2). The
FNM_FILE_NAME, FNM_LEADING_DIR, and FNM_CASEFOLD
flags are GNU extensions.
