See also | struct ncDeviceHandle_t, ncDeviceOption_t, ncDeviceOpen(), ncDeviceClose(), ncDeviceDestroy() |
This function initializes a ncDeviceHandle_t struct.
You must create a separate handle for each neural compute device. Typical multi-device usage is to call this function repeatedly, starting with index = 0 and incrementing the index each time until an error is returned.
ncDeviceDestroy() frees the memory that is allocated with this function.
ncStatus_t ncDeviceCreate(int index, struct ncDeviceHandle_t** deviceHandle);
Name | Type | Description |
---|---|---|
index | int | The zero-based index of a neural compute device. |
deviceHandle | struct ncDeviceHandle_t** | The address of a pointer to a ncDeviceHandle_t struct that will be created and initialized by this function. |
An appropriate value from the ncStatus_t enumeration.
