| stream | - | to read the wide character from |
The next wide character from the stream orWEOF on failure.
If the failure has been caused by end-of-file condition, additionally sets theeof indicator (seefeof()) onstream. If the failure has been caused by some other error, sets theerror indicator (seeferror()) onstream.
If an encoding error occurred, additionally setserrno toEILSEQ.
