## Input Parameter

- ***file -*** the file pointer, or `NULL` to use `PETSC_STDOUT`





## Notes
In debug mode PETSc maintains a stack of the current function calls that can be used to help to quickly see where a problem has
occurred, for example, when a signal is received. It is recommended to use the debugger if extensive information is needed to
help debug the problem.

The default stack is a global variable called `petscstack`.
