FNMATCH(3)	      DragonFly Library Functions Manual	    FNMATCH(3)

NAME

fnmatch -- test whether a filename or pathname matches a shell-style pat- tern

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <fnmatch.h> int fnmatch(const char *pattern, const char *string, int flags);

DESCRIPTION

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 slash. FNM_LEADING_DIR Ignore ``/*'' rest after successful pattern matching. FNM_CASEFOLD Ignore case distinctions in both the pattern and the string.

RETURN VALUES

The fnmatch() function returns zero if string matches the pattern speci- fied by pattern, otherwise, it returns the value FNM_NOMATCH.

SEE ALSO

sh(1), glob(3), regex(3)

STANDARDS

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.

HISTORY

The fnmatch() function first appeared in 4.4BSD.

BUGS

The pattern `*' matches the empty string, even if FNM_PATHNAME is speci- fied. DragonFly 5.3 July 18, 2004 DragonFly 5.3 FNMATCH(3am) GNU Awk Extension Modules FNMATCH(3am)

NAME

fnmatch - compare a string against a filename wildcard

SYNOPSIS

@load "fnmatch" result = fnmatch(pattern, string, flags)

DESCRIPTION

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: FNM["CASEFOLD"] Corresponds to the FNM_CASEFOLD flag as defined in fnmatch(3). FNM["FILE_NAME"] Corresponds to the FNM_FILE_NAME flag as defined in fnmatch(3). FNM["LEADING_DIR"] Corresponds to the FNM_LEADING_DIR flag as defined in fnmatch(3). FNM["NOESCAPE"] Corresponds to the FNM_NOESCAPE flag as defined in fnmatch(3). FNM["PATHNAME"] Corresponds to the FNM_PATHNAME flag as defined in fnmatch(3). FNM["PERIOD"] Corresponds to the FNM_PERIOD flag as defined in fnmatch(3).

NOTES

Nothing prevents AWK code from changing the predefined variabale FNM_NOMATCH, but doing so may cause strange results.

EXAMPLE

@load "fnmatch" ... flags = or(FNM["PERIOD"], FNM["NOESCAPE"]) if (fnmatch("*.a", "foo.c", flags) == FNM_NOMATCH) print "no match"
