| 3 | < |
||
| 4 | |||
| 5 | ANSI_SYNOPSIS |
||
| 6 | #include |
||
| 7 | int wcsncmp(const wchar_t *<[s1]>, const wchar_t *<[s2]>, size_t <[n]>); |
||
| 8 | |||
| 9 | TRAD_SYNOPSIS |
||
| 10 | int wcsncmp(<[s1]>, <[s2]>, <[n]> |
||
| 11 | const wchar_t *<[s1]>; |
||
| 12 | const wchar_t *<[s2]>; |
||
| 13 | size_t <[n]>; |
||
| 14 | |||
| 15 | DESCRIPTION |
||
| 16 | The < |
||
| 17 | codes (wide-character codes that follow a null wide-character code are |
||
| 18 | not compared) from the array pointed to by <[s1]> to the array pointed |
||
| 19 | to by <[s2]>. |
||
| 20 | |||
| 21 | The sign of a non-zero return value is determined by the sign of the |
||
| 22 | difference between the values of the first pair of wide-character codes |
||
| 23 | that differ in the objects being compared. |
||
| 24 | |||
| 25 | RETURNS |
||
| 26 | Upon successful completion, < |
||
| 27 | equal to or less than 0, if the possibly null-terminated array pointed |
||
| 28 | to by <[s1]> is greater than, equal to or less than the possibly |
||
| 29 | null-terminated array pointed to by <[s2]> respectively. |
||
| 30 | |||
| 31 | PORTABILITY |
||
| 32 | < |
||
| 33 | |||
| 34 | No supporting OS subroutines are required. |
