BuildCommDCBAndTimeouts info  Overview  Group

The BuildCommDCBAndTimeouts function translates a device-definition string into appropriate device-control block codes and then places these codes into a device control block. The function can also set up time-out values, including the possibility of no time-outs, for a device; the function’s behavior in this regard varies based on the contents of the device-definition string.

BOOL BuildCommDCBAndTimeouts(

    LPCTSTR lpDef,

// pointer to the device-control string

    LPDCB lpDCB,

// pointer to the device-control block

    LPCOMMTIMEOUTS  lpCommTimeouts 

// pointer to comm. time-out structure

   );

Parameters

lpDef
Pointer to a null-terminated string that specifies device-control information for the device. The function takes this string, parses it, and then sets appropriate values in the DCB structure pointed to by lpDCB.
lpDCB
Pointer to a DCB structure that the function fills with information from the device-control information string pointed to by lpDef. This DCB structure defines the control settings for a communications device.
lpCommTimeouts
Pointer to a COMMTIMEOUTS structure that the function can use to set device time-out values.

The BuildCommDcbAndTimeouts function modifies its time-out setting behavior based on the presence or absence of a “TO=xxx” substring in the string specified by lpDef:

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, call GetLastError.
