Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

VxDcall V86MMGR_Set_Xlat_Buff_State
 
The V86MMGR_Set_Xlat_Buff_State service switches to an alternate mapping
buffer. This feature is provided for protected-mode TSR programs which may
need to switch to a private translation buffer before executing protected
mode MS-DOS calls since the default buffer may be full.
 
A virtual device should get the current translation buffer state, set the
new state, perform any MS-DOS call, and then set the state back to the
original values.
