Return Value: ERR_OK
Description:
Parameters:
int seGetScreenSize(int DevID, int * Width, int * Height)
int seDelay(int MilliSeconds)
int seGetLastUsableByte(int DevID, long * plLastByte)
Retrieves the width and height in pixels of the display surface. The width and height
are derived by reading the horizontal and vertical size registers and calculating the
dimensions. Virtual dimensions are not taken into account for this calculation.
When the display is in SwivelView mode the dimensions will be swapped. (i.e. a
640x480 display in SwivelView mode will return a width and height of 480 and
height of 640.
DevID
Width
Height
This function will delay for the length of time specified in “MilliSeconds” before
returning to the caller.
This function was originally intended for non-PC platforms. Information about how
to access the timers was not always available however we do know frame rate and
can use that for timing calculations.
The SED1374 registers must be initialized for this function to work correctly. On the
PC platform this is simply a call to the C timing functions and is therefore
independent of the register settings.
DevID
MilliSeconds- time to delay in seconds
ERR_FAILED- returned on non-PC platforms when the SED1374 registers have not
bee initialized
This functions returns a pointer, as a long integer, to the last byte of usable display
memory.
This function is a holdover from 135X products which support different amounts of
memory.
DevID
plLastByte - pointer to a long integer to receive the offset to the last byte of
- registered device ID
- pointer to an integer to receive the display width
- pointer to an integer to receive the display height
- the operation completed successfully
- registered device ID
- operation completed with no problems
- registered device ID
