It checks the string specified by the string argument to see if it matches the pattern specified by the pattern argument.
Returns: 0 when matched. if there is no match, fnmatch() shall return FNM_NOMATCH. Non-zero on other errors.
Example:
assert(posix.fnmatch("*.odin", "foo.odin", {}) == 0)
assert(posix.fnmatch("*.txt", "foo.odin", {}) == posix.FNM_NOMATCH)
