GetCommConfig info Overview Group

The GetCommConfig function gets the current configuration of a communications device.

BOOL GetCommConfig(

HANDLE hCommDev,	// handle of communications service
LPCOMMCONFIG lpCC,	// address of comm.configuration structure
LPDWORD lpdwSize	// address of size of buffer
);

Parameters

hCommDev: Identifies the open communications device.
lpCC: Points to the buffer that receives the COMMCONFIG structure.
lpdwSize: Points to a 32-bit variable that specifies the size, in bytes, of the buffer pointed to by lpCC. When the function returns, the variable contains the number of bytes copied if the function succeeds, or the number of bytes required if the buffer was too small.

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, use the GetLastError function.
