Detailed Description
Gets an interprocess memory handle for an existing device memory allocation.
Takes a pointer to the base of an existing device memory allocation created with hipMalloc and exports it for use in another process. This is a lightweight operation and may be called multiple times on an allocation without adverse effects.
If a region of memory is freed with hipFree and a subsequent call to hipMalloc returns memory with the same device address, hipIpcGetMemHandle will return a unique handle for the new memory.
- Parameters
-
handle - Pointer to user allocated hipIpcMemHandle to return the handle in. devPtr - Base pointer to previously allocated device memory
- Returns
- hipSuccess, hipErrorInvalidHandle, hipErrorOutOfMemory, hipErrorMapFailed,
