17 | .SH NAME |
| 18 | wcsncmp \- compare two fixed-size wide-character strings | |
| 19 | .SH SYNOPSIS | |

| 21 | .B #include <wchar.h> | |
| 68e4db0a | 22 | .PP |

| 25 | .SH DESCRIPTION | |
| 60a90ecd MK |
26 | The |
| 27 | .BR wcsncmp () | |
| 28 | function is the wide-character equivalent of the | |
| 29 | .BR strncmp (3) | |
| 30 | function. | |
| 40aa0db0 MK |
31 | It compares the wide-character string pointed to by |
| 32 | .I s1 | |
| 33 | and the | |
| 34 | wide-character string pointed to by | |
| 35 | .IR s2 , | |
| 36 | but at most | |
| 37 | .I n | |
| 38 | wide | |
| c13182ef MK |
39 | characters from each string. |
| 40 | In each string, the comparison extends only up | |
| d1a71985 | 41 | to the first occurrence of a null wide character (L\(aq\e0\(aq), if any. |
| 47297adb | 42 | .SH RETURN VALUE |
| 60a90ecd MK |
43 | The |
| 44 | .BR wcsncmp () | |
| 45 | function returns zero if the wide-character strings at | |
| 40aa0db0 MK |
46 | .I s1 |
| 47 | and | |
| 48 | .IR s2 , | |
| 49 | truncated to at most length | |
| 50 | .IR n , | |
| 51 | are equal. | |
| fea681da | 52 | It returns an integer greater than zero if at the first differing position |
| 40aa0db0 MK |
53 | .I i |
| 54 | .RI ( i | |
| 55 | < | |
| 56 | .IR n ), | |
| 57 | the corresponding wide-character | |
| 58 | .I s1[i] | |
| 59 | is | |
| 60 | greater than | |
| 61 | .IR s2[i] . | |
| c13182ef | 62 | It returns an integer less than zero if at the first |
| 40aa0db0 MK |
63 | differing position |
| 64 | .I i | |
| 2d20cb1b | 65 | .RI ( i |
| 40aa0db0 MK |
66 | < |
| 67 | .IR n ), | |
| 68 | the corresponding | |
| 69 | wide-character | |
| 70 | .I s1[i] | |
| 71 | is less than | |
| 72 | .IR s2[i] . | |
