NAME

fnmatch - match filename or pathname

SYNOPSIS

#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.
