The TSPI_phoneSetDisplay function causes the specified string to be displayed on the specified open phone device.
The identifier of the asynchronous request.
The handle to the phone on which the string is to be displayed.
The row on the display where the new text is to be displayed.
The column position on the display where the new text is to be displayed.
A pointer to the memory location where the display content is stored. The application stores the display information in the format specified as dwStringFormat in the phone's PHONECAPS structure.
The size in bytes, including the null terminator, of the information pointed to by lpDisplay.
Returns dwRequestID, or an error number if an error occurs. The lResult actual parameter of the corresponding ASYNC_COMPLETION is zero if the function succeeds or it is an error number if an error occurs. Possible return values are as follows:
PHONEERR_INVALPHONEHANDLE, PHONEERR_RESOURCEUNAVAIL, PHONEERR_INVALPHONESTATE, PHONEERR_OPERATIONFAILED, PHONEERR_INVALPARAM, PHONEERR_OPERATIONUNAVAIL, PHONEERR_NOMEM.
The specified display information is written to the phone's display, starting at the specified positions. This operation overwrites previously displayed information. If the amount of information exceeds the size of the display, the information is truncated. The amount of information that can be displayed is at most (dwNumRows * dwNumColumns) elements in size. The dwNumRows and dwNumColumns members are available in the PHONECAPS structure returned by TSPI_phoneGetDevCaps; they are zero-based.
