DosError

This call allows an OS/2 process to receive hard error notification without generating a hard error signal.

DosError

(Flag)

Flags (USHORT) - input

Bit field, defined in the following example (the unused high-order bits are reserved and must be set to zero).

Bit

Description
15-2
Reserved, set to zero.
1
0 = Enable exception popups.

1 = Disable exception popups.

0
0 = Disable hard error popups (fail requests).

1 = Enable hard error popups.

rc (USHORT) - return
Return code descriptions are:
• NO_ERROR 87
  ERROR_INVALID_PARAMETER
  Remarks

  DosError allows an OS/2 process to disable user notification if a program (or untrapped numeric processor) exception occurs. If end user notification is disabled, and if one of these exceptions occurs, the process is terminated.

  Hard errors generated under a process that has issued a DosError call are failed, and the appropriate error code is returned. The default situation is both hard error pop-ups and exception pop-ups are enabled, if DosError is not issued.

  
  Family API Considerations

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

  For Flag, a value of 0000 causes all subsequent INT 24s to be failed until a subsequent call with a value of 1 is issued.

  Note: Since INT 24 is not issued in DOS mode, this call has no effect when running in DOS mode.
