By default the 32 debugger is gdb; alternatives are dbx and xxgdb. 33 34 Level: developer 35 36 Notes: 37 Most users need not directly employ this routine and the other error 38 handlers, but can instead use the simplified interface SETERRQ, which 39 has the calling sequence 40 $ SETERRQ(comm,number,mess) 41 or its variants, SETERRQ1(number,formatstring,arg1), SETERRQ2(), ... that 42 allow including arguments in the message. 43 44 Notes for experienced users: 45 Use PetscPushErrorHandler() to set the desired error handler. The 46 currently available PETSc error handlers include PetscTraceBackErrorHandler(), 47 PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler(). 48 49 Concepts: error handler^aborting 50 Concepts: aborting on error 51 52 .seealso: PetscPushErrorHandler(), PetscTraceBackErrorHandler(), 53 PetscAttachDebuggerErrorHandler() 54 @*/ 55 PetscErrorCode PetscAbortErrorHandler(MPI_Comm comm,int line,const char *fun,const char *file,const char *dir,PetscErrorCode n,PetscErrorType p,const char *mess,void *ctx) 56 { 57 PetscFunctionBegin; 58 (*PetscErrorPrintf)("%s() line %d in %s%s %s\n",fun,line,dir,file,mess); 59 abort(); 60 PetscFunctionReturn(0); 61 } 62 63
