The fesetexceptflag function sets the complete status for those

exception flags indicated by the argument excepts, according to the

representation in the object pointed to by flagp. The value of

*flagp shall have been set by a previous call to fegetexceptflag
|
|
whose second argument represented at least those exceptions
|
|
represented by the argument excepts. This function does not raise
|

exceptions, but only sets the state of the flags. */
