Patterns are Unix shell style pattern: + * '*' stands for 0 or more characters, '?' for one single character, a list + * of characters in square brackets for a single character from the list + * (dashes are allowed to specify a range) and if the lis of characters begins + * with a caret ('^'), it matches one character which is NOT in the list. + * Other parameters to the function: If 'warningsFp' is not NULL, warning + * messages are printed to this file descriptor with fprintf().
