# DRV_ETHPHY_Close Function

## C

    void DRV_ETHPHY_Close(DRV_HANDLE handle);

## Returns

None

## Description

This function closes an opened instance of the Ethernet PHY driver, invalidating the handle.

## Remarks

- After calling this routine, the handle passed in "handle" must not be used with any of the remaining driver routines. A new handle must be obtained by calling DRV_ETHPHY_Open before the caller may use the driver again.
- Usually there is no need for the driver client to verify that the Close operation has completed.

## Preconditions

The DRV_ETHPHY_Initialize routine must have been called for the specified Ethernet PHY driver instance. DRV_ETHPHY_Open must have been called to obtain a valid opened device handle.
