cudaMemcpy Interface

public interface cudaMemcpy

Copies data synchronously between host and device.


Functions

private function cudaMemcpy_ptr(dst, src, count, kdir) result(cudaError_t) bind(C, name="cudaMemcpy")

Arguments

Type IntentOptional Attributes Name
type(c_ptr), value :: dst

Destination pointer
type(c_ptr), value :: src

Source pointer
integer(kind=c_size_t), value :: count

Size in bytes to copy
integer(kind=c_int), value :: kdir

Direction of copy

Return Value integer(kind=c_int)

Returns cudaSuccess if the copy was completed successfully, or an error code if there was an issue.

private function cudaMemcpy_r64(dst, src, count, kdir) result(cudaError_t) bind(C, name="cudaMemcpy")

Arguments

Type IntentOptional Attributes Name
real(kind=c_double) :: dst(*)

Destination array (64-bit float)
real(kind=c_double) :: src(*)

Source array (64-bit float)
integer(kind=c_size_t), value :: count

Number of bytes to copy
integer(kind=c_int), value :: kdir

Direction of copy

Return Value integer(kind=c_int)

Returns cudaSuccess if the copy was completed successfully, or an error code if there was an issue.

private function cudaMemcpy_r32(dst, src, count, kdir) result(cudaError_t) bind(C, name="cudaMemcpy")

Destination array (32-bit float)
real(kind=c_float) :: src(*)

Source array (32-bit float)
integer(kind=c_size_t), value :: count

Number of bytes to copy
integer(kind=c_int), value :: kdir

Direction of copy

Return Value integer(kind=c_int)

Returns cudaSuccess if the copy was completed successfully, or an error code if there was an issue.
