Linux 2.6 - man page for fnmatch (linux section 3posix)

FNMATCH(P)			    POSIX Programmer's Manual			       FNMATCH(P)

       fnmatch - match a filename or a pathname

       #include <fnmatch.h>

       int fnmatch(const char *pattern, const char *string, int flags);

       The fnmatch() function shall match patterns as described in the Shell and Utilities volume
       of IEEE Std 1003.1-2001, Section 2.13.1, Patterns Matching a Single Character, and Section
       2.13.2,	Patterns  Matching  Multiple  Characters.   It checks the string specified by the
       string argument to see if it matches the pattern specified by the pattern argument.

       The flags argument shall modify the interpretation of pattern and string. It is	the  bit-
       wise-inclusive OR of zero or more of the flags defined in <fnmatch.h>. If the FNM_PATHNAME
       flag is set in flags, then a slash character ( '/' ) in string shall be explicitly matched
       by  a  slash  in  pattern; it shall not be matched by either the asterisk or question-mark
       special characters, nor by a bracket expression. If the FNM_PATHNAME flag is not set,  the
       slash character shall be treated as an ordinary character.

       If  FNM_NOESCAPE is not set in flags, a backslash character ( '\' ) in pattern followed by
       any other character shall match that second character in string. In particular, "\\" shall
       match  a  backslash  in	string.  If  FNM_NOESCAPE  is set, a backslash character shall be
       treated as an ordinary character.

       If FNM_PERIOD is set in flags, then a leading period ( '.'  )  in  string  shall  match	a
       period  in  pattern;  as  described  by	rule  2  in  the  Shell  and  Utilities volume of
       IEEE Std 1003.1-2001, Section 2.13.3, Patterns Used for Filename Expansion where the loca-
       tion of "leading" is indicated by the value of FNM_PATHNAME:

	* If FNM_PATHNAME is set, a period is "leading" if it is the first character in string or
	  if it immediately follows a slash.

	* If FNM_PATHNAME is not set, a period is "leading" only if it is the first character  of

       If FNM_PERIOD is not set, then no special restrictions are placed on matching a period.

       If  string  matches  the  pattern  specified by pattern, then fnmatch() shall return 0. If
       there is no match, fnmatch() shall return FNM_NOMATCH, which is	defined  in  <fnmatch.h>.
       If an error occurs, fnmatch() shall return another non-zero value.

       No errors are defined.

       The following sections are informative.


       The  fnmatch()  function has two major uses. It could be used by an application or utility
       that needs to read a directory and apply a pattern against each entry. The find utility is
       an  example  of	this. It can also be used by the pax utility to process its pattern oper-
       ands, or by applications that need to match strings in a similar manner.

       The name fnmatch() is intended to imply filename match, rather than  pathname  match.  The
       default	action	of  this  function is to match filenames, rather than pathnames, since it
       gives no special  significance  to  the	slash  character.  With  the  FNM_PATHNAME  flag,
       fnmatch()  does match pathnames, but without tilde expansion, parameter expansion, or spe-
       cial treatment for a period at the beginning of a filename.

       This function replaced the REG_FILENAME flag of regcomp() in early proposals of this  vol-
       ume of IEEE Std 1003.1-2001. It provides virtually the same functionality as the regcomp()
       and regexec() functions using the REG_FILENAME and REG_FSLASH flags (the  REG_FSLASH  flag
       was proposed for regcomp(), and would have had the opposite effect from FNM_PATHNAME), but
       with a simpler function and less system overhead.
