24 | .SH DESCRIPTION | |
60a90ecd MK |
25 | The |
26 | .BR wmemcmp () | |
27 | function is the wide-character equivalent of the | |
28 | .BR memcmp (3) | |
29 | function. | |
35cfd378 | 30 | It compares the |
51700fd7 | 31 | .IR n |
35cfd378 MK |
32 | wide-characters starting at |
33 | .I s1 | |
34 | and the | |
35 | .I n | |
36 | wide-characters starting at | |
37 | .IR s2 . | |

60a90ecd MK |
39 | The |
40 | .BR wmemcmp () | |
41 | function returns | |
c13182ef | 42 | zero if the wide-character arrays of size |
35cfd378 MK |
43 | .I n |
44 | at | |
51700fd7 | 45 | .IR s1 |
35cfd378 MK |
46 | and |
47 | .I s2 | |
48 | are equal. | |

53 | .IR n ), | |
54 | the | |
55 | corresponding wide-character | |
56 | .I s1[i] | |
