EngSetLastError

VOID EngSetLastError(

IN ULONG iError
);

EngSetLastError causes GDI to log an error code. This error code can be retrieved by an application.

Parameters

iError

Specifies the 32-bit error code to set.

Comments

EngSetLastError sets the last error code for the calling thread. This function allows a driver to communicate error conditions to an application. To facilitate this communication, a driver should use the Win32 application error codes defined in winerror.h.

Only the last error code to be set is retrievable; that is, consecutive calls to EngSetLastError will cause the last-error code field to be overwritten.
