5. Error Codes

This chapter describes the error/cause codes supported by the modular station interface (MSI) library, msilib.h. All MSI library functions return a value that indicates the success or failure of the function call. Success is indicated by a return value of zero or a non-negative number. Failure is indicated by a value of -1.

If a function fails, call the Standard Attribute functions ATDV_LASTERR( ) and ATDV_ERRMSGP( ) for the reason for failure. These functions are described in the Standard Runtime Library API Library Reference.

The MSI library contains the following error codes, listed in alphabetical order.
