Exceptions (C/C++)

  • 아티클

 

The latest version of this topic can be found at Exceptions (C/C++).

Two exception codes can be raised when failures are encountered:

  • For a LoadLibrary failure

  • For a GetProcAddress failure

Here is the exception information:

//  
// Exception information  
//  
#define FACILITY_VISUALCPP  ((LONG)0x6d)  
#define VcppException(sev,err)  ((sev) | (FACILITY_VISUALCPP<<16) | err)

The exception codes thrown are the standard VcppException(ERROR_SEVERITY_ERROR, ERROR_MOD_NOT_FOUND) and VcppException(ERROR_SEVERITY_ERROR, ERROR_PROC_NOT_FOUND) values. The exception passes a pointer to a DelayLoadInfo structure in the LPDWORD value that can be retrieved by GetExceptionInformation in the EXCEPTION_RECORD structure, ExceptionInformation[0] field.

Additionally, if the incorrect bits are set in the grAttrs field, the exception ERROR_INVALID_PARAMETER is thrown. This exception is, for all intents and purposes, fatal.

See Structure and Constant Definitions for more information.
