| 6 | ANSI_SYNOPSIS |
||
| 7 | #include |
||
| 8 | wchar_t *wmemchr(const wchar_t *<[s]>, wchar_t <[c]>, size_t <[n]>); |
||
| 9 | |||
| 10 | TRAD_SYNOPSIS |
||
| 11 | wchar_t *wmemchr(<[s]>, <[c]>, <[n]> |
||
| 12 | const wchar_t *<[s]>; |
||
| 13 | wchar_t <[c]>; |
||
| 14 | size_t <[n]>; |
||
| 15 | |||
| 16 | DESCRIPTION |
||
| 17 | The < |
||
| 18 | initial <[n]> wide characters of the object pointed to be <[s]>. This |
||
| 19 | function is not affected by locale and all wchar_t values are treated |
||
| 20 | identically. The null wide character and wchar_t values not |
||
| 21 | corresponding to valid characters are not treated specially. |
||
| 22 | |||
| 23 | If <[n]> is zero, <[s]> must be a valid pointer and the function |
||
| 24 | behaves as if no valid occurrence of <[c]> is found. |
||
| 25 | |||
| 26 | RETURNS |
||
| 27 | The < |
||
| 28 | wide character, or a null pointer if the wide character does not occur |
||
| 29 | in the object. |
||
| 30 | |||
| 31 | PORTABILITY |
||
| 32 | < |
||
| 33 | |||
| 34 | No supporting OS subroutines are required. |
