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 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 the FNM_NOESCAPE flag 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 string must be explicitly matched by
periods in 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 string. Additionally, if FNM_PATHNAME
is set, a period is leading if it immediately follows a
Ignore ``/*'' rest after successful pattern matching.

The fnmatch() function returns zero if string matches the pattern speci-
fied 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 speci-

FNMATCH(3am) GNU Awk Extension Modules FNMATCH(3am)
fnmatch - compare a string against a filename wildcard
result = fnmatch(pattern, string, flags)
The fnmatch extension provides an AWK interface to the fnmatch(3) rou-
tine. It adds a single function named fnmatch(), one predefined vari-
able (FNM_NOMATCH), and an array of flag values named FNM.
The first argument is the filename wildcard to match, the second is the
filename string, and the third is either zero, or the bitwise OR of one
or more of the flags in the FNM array.
The return value is zero on success, FNM_NOMATCH if the string did not
match the pattern, or a different non-zero value if an error occurred.
The flags are follows:
Corresponds to the FNM_CASEFOLD flag as defined in fnmatch(3).
Corresponds to the FNM_FILE_NAME flag as defined in fnmatch(3).
Corresponds to the FNM_LEADING_DIR flag as defined in
Corresponds to the FNM_NOESCAPE flag as defined in fnmatch(3).
Corresponds to the FNM_PATHNAME flag as defined in fnmatch(3).
Corresponds to the FNM_PERIOD flag as defined in fnmatch(3).
Nothing prevents AWK code from changing the predefined variabale
FNM_NOMATCH, but doing so may cause strange results.
flags = or(FNM["PERIOD"], FNM["NOESCAPE"])
if (fnmatch("*.a", "foo.c", flags) == FNM_NOMATCH)
print "no match"
