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.

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.
The value to be returned.
