DosGetCp

This call allows a process to query the current process code page and the prepared system code pages.

DosGetCp

(Length, CodePageList, DataLength)

Length (USHORT) - input

Length, in bytes, of CodePageList. This length should be at least 2 bytes. If the length is less than the bytes needed to return all the prepared system code pages than the returned CodePageList is truncated.
CodePageList (PUSHORT) - output
Address of the list of available system code pages. The format of the information returned in this list is:

Word

Description
1
Current code page identifier
2
The first prepared code page
3
The second prepared code page
N
Other prepared system code pages.
DataLength (PUSHORT) - output
Address of the length, in bytes, of the returned data.
rc (USHORT) - return
Return code descriptions are:
• NO_ERROR 473
  ERROR_CPLIST_TOO_SMALL
  Remarks

  If the process code page identifier was previously set by DosSetCp or inherited by a process, it is returned to the caller.

  An input list size (length) of two bytes returns only the current process code page identifier. If CodePageList length is too small to hold all the available information, then as much information as possible is provided in the available space and ERROR_CPLIST_TOO_SMALL is returned.

  If no codepages were prepared with the CODEPAGE command, a length of two and current codepage identifier value of zero is returned.

  
  Family API Considerations

  Some options operate differently in the DOS mode than in OS/2 mode. Therefore, the following restriction applies to DosGetCp when coding for the DOS mode:

  The current process code page, and no more than one prepared system code page, is returned.
