.Dt FNMATCH 3
.Os
.Sh NAME
.Nm fnmatch
.Nd match filename or pathname using shell glob rules
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In fnmatch.h
.Ft int
.Fn fnmatch "const char *pattern" "const char *string" "int flags"
.Sh DESCRIPTION
The
.Fn fnmatch
function
matches patterns according to the globbing rules used by the shell.
It checks the string specified by the
.Fa string
argument to see if it matches the pattern specified by the
.Fa pattern
argument.
.Pp
The
.Fa flags
argument modifies the interpretation of
.Fa pattern
and
.Fa string .
The value of
.Fa flags
is the bitwise inclusive
.Tn OR
of any of the following
constants, which are defined in the include file
.Pa fnmatch.h .
.Bl -tag -width FNM_LEADING_DIRXX
.It Dv FNM_NOESCAPE
Normally, every occurrence of a backslash
.Pq Ql \e
followed by a character in
.Fa pattern
is replaced by that character.
This is done to negate any special meaning for the character.
If the
.Dv FNM_NOESCAPE
flag is set, a backslash character is treated as an ordinary character.
.It Dv FNM_PATHNAME
Slash characters in
.Fa string
must be explicitly matched by slashes in
.Fa pattern .
If this flag is not set, then slashes are treated as regular characters.
.It Dv FNM_PERIOD
Leading periods in strings match periods in patterns.
The definition of ``leading'' is related to the specification of
.Dv FNM_PATHNAME .
A period is always ``leading'' if it is the first character in
.Ar string .
Additionally, if
.Dv FNM_PATHNAME
is set,
a period is ``leading'' if it immediately follows a slash.
.It Dv FNM_LEADING_DIR
Ignore
.Dq /*
rest after successful
.Fa pattern
matching.
.It Dv FNM_CASEFOLD
The pattern is matched in a case-insensitive fashion.
.El
.Sh RETURN VALUES
The
.Fn fnmatch
function returns zero if
.Fa string
matches the pattern specified by
.Fa pattern ,
otherwise, it returns the value
.Dv FNM_NOMATCH .
.Sh SEE ALSO
.Xr sh 1 ,
.Xr glob 3 ,
.Xr regex 3 ,
.Xr glob 7
.Sh STANDARDS
The
.Fn fnmatch
function conforms to
.St -p1003.2-92 .
The
.Dv FNM_CASEFOLD
flag is a
.Nx
extension.
.Sh HISTORY
The
.Fn fnmatch
function first appeared in
.Bx 4.4 .
.Sh BUGS
The pattern
.Ql *
matches the empty string, even if
.Dv FNM_PATHNAME
is specified.
