+ * Name: fnmatch
+ *
+ * Description:
+ *   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 bitwise-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 location 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 string.
+ *
+ *   If FNM_PERIOD is not set, then no special restrictions are placed on
+ *   matching a period.
+ *
+ * Returned Value:
+ *   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.
