19 | DESCRIPTION |
||
20 | < |
||
21 | from the string at <[a]> to the string at <[b]> in a |
||
22 | case-insensitive manner. |
||
23 | |||
24 | RETURNS |
||
25 | |||
26 | If <<*<[a]>>> sorts lexicographically after <<*<[b]>>> (after |
||
27 | both are converted to lowercase), < |
||
28 | number greater than zero. If the two strings are equivalent, |
||
29 | < |
||
30 | lexicographically before <<*<[b]>>>, < |
||
31 | number less than zero. |
||
32 | |||
33 | PORTABILITY |

||
37 | tolower() from elsewhere in this library. |
