Locates first occurrence of a wide character in a string.


Standard C Library (libc.a)


#include <string.h>

wchar_t *wcswcs(WcString1WcString2)

The wcswcs subroutine locates the first occurrence, in the string pointed to by the WcString1 parameter, of a sequence of wchar_t characters (excluding the terminating wchar_t null character) from the string pointed to by the WcString2 parameter.


WcString1 Points to the wide-character string being searched.
