OEMKeyScan

DWORD OEMKeyScan(
  WORD wOemChar
 );

Maps OEM codes (0 through 0FFH) into scan codes and shift states. This function provides information that enables a program to send OEM text to another program by simulating keyboard input. Windows, when running in 386 enhanced mode, uses it specifically for this purpose.

Returns the scan code in AX and the shift state in DX. If the character is not defined in the tables, the return value is -1 in both DX and AX.

wOemChar: ASCII character.

The export ordinal for this function is 128.

The bits in the shift state returned in DX have the following meaning.

Bit	Value
1	1 if the SHIFT key is down; 0 otherwise.
2	1 if CTRL and SHIFT is down; 0 otherwise.

This function does not provide translations for characters that require the CTRL+ALT key combination or dead keys.

This function calls VkKeyScan.
