wildmat - perform shell-style wildcard matching
int
wildmat(text, pattern)
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...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.
