FNMATCH(3) BSD Library Functions Manual FNMATCH(3)
fnmatch -- match filename or pathname using shell glob rules
Standard C Library (libc, -lc)
fnmatch(const char *pattern, const char *string, int flags);
The fnmatch() 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 spec-
ified 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
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
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,
if FNM_PATHNAME is set, a period is ``leading'' if it immediately follows
FNM_LEADING_DIR Ignore ``/*'' rest after successful pattern matching.
FNM_CASEFOLD The pattern is matched in a case-insensitive fashion.
The fnmatch() function returns zero if string matches the pattern specified by pattern, oth-
erwise, it returns the value FNM_NOMATCH.

The fnmatch() function conforms to IEEE Std 1003.2-1992 (``POSIX.2''). The FNM_CASEFOLD
flag is a NetBSD extension.
The fnmatch() function first appeared in 4.4BSD.
The pattern '*' matches the empty string, even if FNM_PATHNAME is specified.
