Return Code

fSuccess (BOOL) - returns

On completion, the handling routine must return BOOLEAN (fSuccess).
  • TRUE Successful
  • FALSE Error
Possible Errors Detected: When an error is detected, the graphics engine calls WinSetErrorInfo to post the condition. Reasons for failure of this function include:
  • PMERR_BASE_ERROR
  • PMERR_FONT_FILE_NOT_LOADED
Refer to the "Error Explanations" section of the Presentation Manager Programming Reference for further explanation.

  • The fonts are not in use for the current character set.
  • The relevant lcids have been deleted (see GreDeleteSetId).
