By default the 28 debugger is gdb; alternatives are dbx and xxgdb. 29 30 Level: developer 31 32 Notes: 33 Most users need not directly employ this routine and the other error 34 handlers, but can instead use the simplified interface SETERRQ, which 35 has the calling sequence 36 $ SETERRQ(comm,number,mess) 37 or its variants, SETERRQ1(number,formatstring,arg1), SETERRQ2(), ... that 38 allow including arguments in the message. 39 40 Notes for experienced users: 41 Use PetscPushErrorHandler() to set the desired error handler. The 42 currently available PETSc error handlers include PetscTraceBackErrorHandler(), 43 PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler(). 44 45 Concepts: error handler^aborting 46 Concepts: aborting on error 47 48 .seealso: PetscPushErrorHandler(), PetscTraceBackErrorHandler(), 49 PetscAttachDebuggerErrorHandler() 50 @*/ 51 PetscErrorCode PetscAbortErrorHandler(MPI_Comm comm,int line,const char *fun,const char *file,PetscErrorCode n,PetscErrorType p,const char *mess,void *ctx) 52 { 53 PetscFunctionBegin; 54 (*PetscErrorPrintf)("%s() line %d in %s %s\n",fun,line,file,mess); 55 abort(); 56 PetscFunctionReturn(0); 57 } 58 59
