GetCommTimeouts

BOOL GetCommTimeouts(hCommDev, lpct)
HANDLE hCommDev;	/* identifies the comm device	*/
LPCOMMTIMEOUTS lpct;	/* address of structure for timeout values	*/

The GetCommTimeouts function retrieves the timeout characteristics for read and write operations on the specified communications device.

Parameters

hCommDev

Identifies the communication device to query for timeout values. The CreateFile function returns this value.

lpct

Points to a COMMTIMEOUTS structure for the current communications timeout values.

The COMMTIMEOUTS structure has the following format:

typedef struct _COMMTIMEOUTS { /* ctmo */

DWORD ReadIntervalTimeout;

DWORD ReadTotalTimeoutMultiplier;

DWORD ReadTotalTimeoutConstant;

DWORD WriteTotalTimeoutMultiplier;

DWORD WriteTotalTimeoutConstant;

} COMMTIMEOUTS,*LPCOMMTIMEOUTS;

Return Value

The return value is TRUE if the function was successful, or FALSE if an error occurred. Use the GetLastError function to obtain extended error information.

Comments

See the SetCommTimeouts function for more information about the timeout values.
