public function cudaMalloc(ptr, count) result(cudaError_t) bind(C, name="cudaMalloc")

Arguments

Type IntentOptional Attributes Name
type(c_ptr) :: ptr

Pointer to allocated device memory
integer(kind=c_size_t), value :: count

Requested allocation size in bytes

Return Value integer(kind=c_int)

Returns cudaSuccess if memory was allocated successfully, or cudaErrorMemoryAllocation if the memory could not be allocated.
