I mean, literally, what you type for head, character by character. (file name) isn't your real filename so I can't tell if your glob's wrong.

NAME
fnmatch() - match filename patterns SYNOPSIS
DESCRIPTION
performs pattern matching as described in regexp(5) under By default, the rule qualifications for filename expansion do not apply; i.e., periods (dots) and slashes are matched as ordinary characters. This default behavior can be modified by using the flags described below. The flag argument modifies the interpretation of pattern and string. If which is defined in is set in flag, a slash character in string must be explicitly matched by a slash in pattern; it cannot be matched by either the asterisk or question mark special characters or by a bracket expression. If is set in flag, a leading period must be explicitly matched. It will not be matched by a bracket expression, question mark or asterisk. By default, a period is leading if it is the first character in string. If is set in flag, a period is leading if it is the first charac- ter in string or immediately follows a slash. If is not set in flag, a backslash character in pattern followed by any other character matches that second character in string. In par- ticular, matches a backslash in string. If is set, a backslash character is treated as an ordinary character. If flag is zero, the slash character and the period are treated as regular characters. If flag has any other value, the result is unde- fined. RETURN VALUE
If string matches the pattern specified by pattern, returns zero. Otherwise, returns non-zero. EXAMPLE
The following excerpt uses to check each file in a directory against the pattern pattern = "*.c"; while(dp = readdir(dirp)){ if((fnmatch(pattern, dp->d_name,0)) == 0){ /* do processing for match */ ... } } AUTHOR
