|
* This function compares two strings as if they were being used in |
| 2976 |
|
* an index or card catalog. The case of alphabetic characters is |
| 2977 |
|
* ignored, except to break ties. Thus "B" comes before "b" but |
| 2978 |
|
* after "a". Also, integers embedded in the strings compare in |
| 2979 |
|
* numerical order. In other words, "x10y" comes after "x9y", not |
| 2980 |
|
* before it as it would when using strcmp(). |
| 2981 |
|
* |
| 2982 |
|
* Results: |
| 2983 |
|
* A negative result means that the first element comes before the |
| 2984 |
|
* second, and a positive result means that the second element |
| 2985 |
|
* should come first. A result of zero means the two elements |
| 2986 |
|
* are equal and it doesn't matter which comes first. |
| 2987 |
|
* |
| 2988 |
|
* Side effects: |
| 2989 |
|
* None. |
