This function returns whether the program is executing on a particular device specified in devicetype. In C/C++ a non-zero value is returned to indicate the device is execiting on the specified device type. In Fortran, true will be returned. If the program is not executing on the specified device type C/C++ will return a zero, while Fortran will return false.

Prototype: acc_on_device(acc_device_t devicetype);


Interface: function acc_on_device(devicetype)
integer(acc_device_kind) devicetype
logical acc_on_device
