| 37 | .SH DESCRIPTION | |
| 60a90ecd MK |
38 | The |
| 39 | .BR strcoll () | |
| 40 | function compares the two strings \fIs1\fP and | |
| 1c44bd5b MK |
41 | \fIs2\fP. |
| 42 | It returns an integer less than, equal to, or greater | |
| c13182ef | 43 | than zero if \fIs1\fP is found, respectively, to be less than, |
| 1c44bd5b MK |
44 | to match, or be greater than \fIs2\fP. |
| 45 | The comparison is based on | |
| c13182ef | 46 | strings interpreted as appropriate for the program's current locale |
| 60a90ecd MK |
47 | for category \fILC_COLLATE\fP. (See |
| 48 | .BR setlocale (3)). | |

| 60a90ecd MK |
50 | The |
| 51 | .BR strcoll () | |
| 52 | function returns an integer less than, equal to, | |
| c13182ef | 53 | or greater than zero if \fIs1\fP is found, respectively, to be less |
| fea681da MK |
54 | than, to match, or be greater than \fIs2\fP, when both are interpreted |
| 55 | as appropriate for the current locale. | |
