DWCError DWC_GetLastError( int* errorCode );
DWCError DWC_GetLastErrorEx( int* errorCode, DWCErrorType* errorType );
Gets information about the last communication error. If this goes into an error status, the DWC library stops accepting most functions. To recover from an error status, call the DWC_ClearError function after executing the appropriate error handling process.
The error code that should be displayed when the application generates an error is returned to the buffer indicated by the pointer to the error code storage destination. Because the error code is returned as a negative value, invert the sign to make it positive before displaying it on the screen. However, if the error code is 0 or the error process type is DWC_ETYPE_LIGHT, these are game-specific displays and displaying the error code is unnecessary.
We recommend that you use the DWC_GetLastErrorEx function, which also obtains the error process type (errorType) at the same time. errorType stores information about the recovery process after an error occurs, and information for displaying the error code, allowing a fixed error process to be created for each value.
errorCode |
Pointer to the error code storage location. If the error code is not required, specify NULL. |
errorType |
Pointer to location where the error processing type is stored. If the error code is not required, specify NULL. |
Error codes related to the GameSpy SDK (-60000 to -99999)
Error codes for the download feature (-31000 to -31999)
Error codes related to checking for illegal character strings (-33000 to -33999)
Error codes for the authentication server (-20000 to -29999)
