Description and return value

The soc_eof() function returns a value !=0 if the EOF condition applies to socket s; otherwise, soc_eof() returns the value 0.

The soc_error() function returns a value !=0 if a read or write error has occurred on socket s; otherwise, soc_error() returns the value 0. The error indicator remains set until it is deleted with the soc_clearerr() function.

The soc_clearerr() function deletes the error indicator for socket s.
