Attempts to obtain the full contents of the floating-point exception flags that are listed in the bitmask argument excepts, which is a bitwise OR of the floating point exception macros.

The full contents of a floating-point exception flag is not necessarily a boolean value indicating whether the exception is raised or cleared. For example, it may be a struct which includes the boolean status and the address of the code that triggered the exception. This function obtains all such content and stored it in flagp in implementation-defined format.

Parameters

flagp	-	pointer to an Template:cpp object where the flags will be stored
excepts	-	bitmask listing the exception flags to get

Return value

Template:cpp if the flags were successfully stored in flagp, non-zero otherwise.
