WILDMAT(3)


NAME

  wildmat - perform shell-style wildcard matching


SYNOPSIS

  int
  wildmat(text, pattern)
      char		  *text;
      char		  *pattern;


DESCRIPTION

  Wildmat is part of libinn(3).	 Wildmat compares the text against the
  pattern and returns non-zero if the pattern matches the text.	 The pattern
  is interpreted according to rules similar to shell filename wildcards, and
  not as a full regular expression such as those handled by the grep(1)
  family of programs or the regex(3) or regexp(3) set of routines.

  The pattern is interpreted as follows:

  \x   Turns off the special meaning of x and matches it directly; this is
       used mostly before a question mark or asterisk, and is not special
       inside square brackets.

  ?    Matches any single character.

  *    Matches any sequence of zero or more characters.

  [x...y]
       Matches any single character specified by the set x...y.	 A minus sign
       may be used to indicate a range of characters.  That is, [0-5abc] is a
       shorthand for [012345abc].  More than one range may appear inside a
       character set; [0-9a-zA-Z._] matches almost all of the legal
       characters for a host name.  The close bracket, ], may be used if it
       is the first character in the set.  The minus sign, -, may be used if
       it is either the first or last character in the set.

  [^x...y]
       This matches any character not in the set x...y, which is interpreted
       as described above.  For example, [^]-] matches any character other
       than a close bracket or minus sign.

  Lars Mathiesen <thorinn@diku.dk> enhanced the multi-asterisk failure mode
  in early 1991.

  Rich and Lars increased the efficiency of star patterns and reposted it to
  comp.sources.misc in April, 1991.

  Robert Elz <kre@munnari.oz.au> added minus sign and close bracket handling
  in June, 1991.
