GetCommConfig
[Now
Supported on Windows NT]
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.
Return Values
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.
