Video Function Calls

This section reflects the Video API interface of OS/2 only. 

If ERROR_VIO_SEE_ERROR_LOG is returned, further information about the 
error that occurred can be obtained by calling WinGetLast Error. 

Notes: 

  1. Calls marked xPM are not supported by Presentation Manager, and must 
     not be used by Presentation Manager applications.  An error code is 
     returned if any of these calls are issued. 

  2. Calls marked xWPM are not windowable and are not supported by 
     Presentation Manager.  They can be used in OS/2 mode. 

  3. Calls marked FAPI are present in the Family API.
