\fBshpat_match\fR \- match filename or pathname
#include <\fBshpat_match.h\fR>
int \fBshpat_match\fR(const char *\fIpattern\fR, const char *\fIstring\fR, int \fIflags\fR);
int \fBshpat_match_hasglobchar\fR(const char *\fIpattern\fR);
The \fIshpat_match\fR\|(3) function matches patterns according to the rules used by the
shell.  It checks the string specified by the \fIstring\fR argument to see if it
matches the pattern specified by the \fIpattern\fR argument.
.Sh "Shell Patterns"
A \fIpattern\fR consists of normal characters, which match themselves, and
meta-characters (aka \fIglob chars\fR).  The meta-characters are ``\f(CW!\fR'\*(R',
``\f(CW*\fR'\*(R', ``\f(CW?\fR'\*(R', and ``\f(CW[\fR'\*(R'.  These characters lose their special
meanings if they are quoted with a backslash (``\f(CW\e\fR''). 
An asterisk (``\f(CW*\fR'') matches any string of characters.  A question mark
(``\f(CW?\fR'') matches any single character.  A left bracket (``\f(CW[\fR'') introduces
a character class.  The end of the character class is indicated by a ``\f(CW]\fR'\*(R';
if the ``\f(CW]\fR'\*(R' is missing then the ``\f(CW[\fR'\*(R' matches a ``\f(CW[\fR'\*(R' rather than
introducing a character class.  A character class matches any of the
characters between the square brackets.  A range of characters may be
specified using a minus sign (``\f(CW-\fR''). The character class may be
complemented/negated by making an exclamation point (``\f(CW!\fR'') the first
character of the character class.
To include a ``\f(CW]\fR'\*(R' in a character class, make it the first character listed
(after the ``\f(CW!\fR'\*(R', if any).  To include a minus sign, make it the first or
last character listed.
.Sh "Matching Interpretation"
The \fIflags\fR argument modifies the interpretation of \fIpattern\fR and \fIstring\fR
The value of \fIflags\fR is the bitwise inclusive \fI\s-1OR\s0\fR of any of the following
constants, which are defined in the include file \f(CWshpat_match.h\fR.
Normally, every occurrence of a backslash (``\f(CW\e\fR'') followed by a character
in \fIpattern\fR is replaced by that character.  This is done to negate any
special meaning for the character.  If the \f(CWFNM_NOESCAPE\fR flag is set, a
backslash character is treated as an ordinary character.
Slash characters in \fIstring\fR must be explicitly matched by slashes in
\fIpattern\fR If this flag is not set, then slashes are treated as regular
Leading periods in \fIstring\fR must be explicitly matched by periods in
\fIpattern\fR If this flag is not set, then leading periods are treated as
regular characters.  The definition of ``leading'\*(R' is related to the
specification of \f(CWFNM_PATHNAME\fR A period is always ``leading'\*(R' if it is the
first character in \fIstring\fR Additionally, if \fI\s-1FNM_PATHNAME\s0\fR is set, a period
is ``leading'\*(R' if it immediately follows a slash.
Ignore ``\f(CW/*\fR'\*(R' rest after successful \fIpattern\fR matching.
Ignore case distinctions in both the \fIpattern\fR and the \fIstring\fR.
The \fIshpat_match\fR\|(3) function returns zero if \fIstring\fR matches the pattern
specified by \fIpattern\fR, otherwise, it returns the value \f(CWFNM_NOMATCH\fR.
The pattern ``\f(CW*\fR'\*(R' matches the empty string, even if \f(CWFNM_PATHNAME\fR is
\fIsh\fR\|(1), \fIshpat_glob\fR\|(3).
The \fIshpat_match\fR\|(3) function conforms to IEEE Std1003.2 (``POSIX.2'')
The \fIshpat_match\fR\|(3) function is derived from the \fIfnmatch\fR\|(3) function of FreeBSD
3.1 which itself derived it from 4.4BSD.  The \fIshpat_match_hasglobchar\fR\|(3)
function is derived from the \fIap_is_fnmatch\fR\|(3) function of Apache 1.3.
