By default the 35 debugger is gdb; alternatives are dbx and xxgdb. 36 37 Level: developer 38 39 Notes: 40 Most users need not directly employ this routine and the other error 41 handlers, but can instead use the simplified interface SETERRQ, which 42 has the calling sequence 43 $ SETERRQ(comm,number,mess) 44 or its variants, SETERRQ1(number,formatstring,arg1), SETERRQ2(), ... that 45 allow including arguments in the message. 46 47 Notes for experienced users: 48 Use PetscPushErrorHandler() to set the desired error handler. The 49 currently available PETSc error handlers include PetscTraceBackErrorHandler(), 50 PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler(). 51 52 Concepts: error handler^aborting 53 Concepts: aborting on error 54 55 .seealso: PetscPushErrorHandler(), PetscTraceBackErrorHandler(), 56 PetscAttachDebuggerErrorHandler() 57 @*/ 58 PetscErrorCode PETSCSYS_DLLEXPORT PetscAbortErrorHandler(MPI_Comm comm,int line,const char *fun,const char *file,const char* dir,PetscErrorCode n,PetscErrorType p,const char *mess,void *ctx) 59 { 60 PetscFunctionBegin; 61 (*PetscErrorPrintf)("%s() line %d in %s%s %s\n",fun,line,dir,file,mess); 62 abort(); 63 PetscFunctionReturn(0); 64 } 65 66
