int PetscTraceBackErrorHandler(int line,char *fun,char* file,char *dir,int n,int p,char *mess,void *ctx)
Not Collective

Input Parameters

line - the line number of the error (indicated by __LINE__)
func - the function where error is detected (indicated by __FUNCT__)

dir - the directory of the file (indicated by __SDIR__)

Notes

Most users need not directly employ this routine and the other error handlers, but can instead use the simplified interface SETERRQ, which has the calling sequence 
    SETERRQ(number,p,mess)

Notes for experienced users

Use PetscPushErrorHandler() to set the desired error handler. The currently available PETSc error handlers include PetscTraceBackErrorHandler(), PetscAttachDebuggerErrorHandler(), PetscAbortErrorHandler(), and PetscStopErrorHandler()
