Function Documentation

◆ _handle_error()

double _handle_error	(	char *	fname,
		int	opcode,
		unsigned long long	value,
		int	type,
		int	flags,
		int	error,
		double	arg1,
		double	arg2,
		int	nargs
	)

Handles an error condition.

Parameters

fname	- The name of the function that caused the error.
opcode	- Opcode of the function that cause the error (see OP_* consants in fpieee.h).
value	- The value to be returned, encoded as uint64_t.
type	- The type of error (see _DOMAIN, ... in math.h)
flags	- Exception flags (see AMD_F_* constants).
error	- Specifies the CRT error code (EDOM, ...).
arg1	- First parameter to the function that cause the error.
arg2	- Second parameter to the function that cause the error.
nargs	- Number of parameters to the function that cause the error.

Returns: The value to be returned.
