# PetscMPIAbortErrorHandler
Calls PETSCABORT and exits. 
## Synopsis
```
#include "petscsys.h" 
PetscErrorCode PetscMPIAbortErrorHandler(MPI_Comm comm, int line, const char *fun, const char *file, PetscErrorCode n, PetscErrorType p, const char *mess, void *ctx)
```
Not Collective


## Input Parameters

- ***comm -*** communicator over which error occurred
- ***line -*** the line number of the error (indicated by __LINE__)
- ***file -*** the file in which the error was detected (indicated by __FILE__)
- ***mess -*** an error text string, usually just printed to the screen
- ***n -*** the generic error number
- ***p -*** `PETSC_ERROR_INITIAL` if error just detected, otherwise `PETSC_ERROR_REPEAT`
- ***ctx -*** error handler context





## Note
Users do not directly call this routine

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