# PetscReturnErrorHandler
Error handler that causes a return without printing an error message. 
## Synopsis
```
#include "petscsys.h" 
PetscErrorCode PetscReturnErrorHandler(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 -*** specific error number
- ***ctx -*** error handler context





## 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
```none
SETERRQ(comm,number,mess)
```

`PetscIgnoreErrorHandler()` does the same thing as this function, but is deprecated, you should use this function.

Use `PetscPushErrorHandler()` to set the desired error handler.
