Function std.path.filenameCmp

Compares file names and returns

int filenameCmp(CaseSensitive cs = CaseSensitive.osDefault, Range1, Range2) (
  Range1 filename1,
  Range2 filename2
if (isInputRange!Range1 && !isInfinite!Range1 && isSomeChar!(ElementEncodingType!Range1) && !isConvertibleToString!Range1 && isInputRange!Range2 && !isInfinite!Range2 && isSomeChar!(ElementEncodingType!Range2) && !isConvertibleToString!Range2);

Individual characters are compared using filenameCharCmp!cs, where cs is an optional template parameter determining whether the comparison is case sensitive or not.

Treatment of invalid UTF encodings is implementation defined.


cs case sensitivity
filename1 range for first file name
filename2 range for second file name


< 0 if filename1 < filename2, 0 if filename1 == filename2 and > 0 if filename1 > filename2.
