PARAMETERS

s1Specifies the wide-character string being searched. 

s2Specifies the wide-character substring to be located. 

DESCRIPTION

The wcsstr() function locates the first occurrence in the wide-character string pointed to by the s1 parameter of the sequence of wide characters in the wide-character string pointed to by the s2 parameter, excluding the terminating null wide character. 

RETURN VALUES

Upon successful completion, the wcsstr() function returns a pointer to the located wide-character substring or a null pointer when the substring is not found. If the s2 parameter points to a wide-character substring having 0 (zero) length, the wcsstr() function returns the entire wide-character string pointed to by parameter s1.
