 +==== VioGetCp ====
 +
 +**Bindings**: C, MASM 
 +
 +This call allows a process to query the code page currently used to display text data. 
 +
 +//VioGetCp// (Reserved, CodePageID, VioHandle) 
 +
 +//Reserved// (**USHORT**) - input 
 +A reserved word of 0s. 
 +
 +//CodePageID// (**PUSHORT**) - output 
 +Address of a word in the application's data area. The current video code page is returned in this word. 
 +
 +//VioHandle// (**HVIO**) - input 
 +This must be zero unless the caller is a Presentation Manager application, in which case it must be the value returned by [[en:ibm:prcp:vio:getps|VioGetPs]]. 
 +
 +//rc// (**USHORT**) - return 
 +Return code descriptions are: 
 +
 +|0 |NO_ERROR |
 +|355 |ERROR_VIO_MODE |
 +|436 |ERROR_VIO_INVALID_HANDLE |
 +|465 |ERROR_VIO_DETACHED |
 +|468 |ERROR_VIO_USER_FONT |
 +
 +**Remarks** 
 +
 +The display code page ID previously set by [[en:ibm:prcp:vio:setcp|VioSetCp]], or inherited from the requesting process, is returned to the caller. 
 +
 +The code page tag returned is the currently active code page. A value of 0000 indicates that the code page in use is the ROM code page provided by the hardware. 
 +
 +If ERROR_VIO_USER_FONT is returned, it indicates a user font that was previously loaded with [[en:ibm:prcp:vio:setfont|VioSetFont]] is the active code page.
