wcsstr ? locate a substring in a wide-character string |
#include <wchar.h> wchar_t *wcsstr (const wchar_t *haystack, const wchar_t *needle); |
The wcsstr function is the wide-character equivalent of the strstr function. It searches for the first occurrence of the wide-character string needle (without its terminating L’\0’ character) as a substring in the wide-character string haystack. |
The wcsstr function returns a pointer to the first occurrence of needle in haystack. It returns NULL if needle does not occur as a substring in haystack. Note the special case: If needle is the empty wide-character string, the return value is always haystack itself. |
