Translates scan codes with shift states into ASCII codes.
Syntax
KbdXlate(pKey, hkbd)
Parameters
- pKey (PKBDKEYINFO) - in/out
- Pointer to character data.
- A pointer to a KBDKEYINFO structure containing character data.
- hkbd (HKBD) - input
- Reserved. Must be 0.
Return Code
- rc (APIRET) - returns
- KbdXlate returns one of the following values:
- 0 - NO_ERROR
- 376 - ERROR_KDB_INVALID_LENGTH
- 439 - ERROR_KBD_INVALID_HANDLE
- 445 - ERROR_KBD_FOCUS_REQUIRED
- 447 - ERROR_KBD_KEYBOARD_BUSY
- 504 - ERROR_KBD_EXTENDED_SG
Sample
#define INCL_KBD #include <os2.h> PKBDKEYINFO pKey; /* Pointer to character data. */ HKBD hkbd; /* Reserved. Must be 0. */ APIRET rc; /* Return code. */ rc = KbdXlate(pKey, hkbd);
Remarks
KbdXlate is designed for conditions where the scan codes are known, but not the character. This must be used with care, and is not designed to be a substitute for the normal OS/2 keyboard translation functions.
The bNlsShift member of KBDKEYINFO must be maintained from call to call whenever an interim bit is set.
