# PetscStackPush
Pushes a new function name and line number onto the PETSc default stack that tracks where the running program is currently in the source code and verifies the memory is not corrupted. 
## Synopsis
```
#include <petscsys.h>
void PetscStackPush(char *funct)
```
Not Collective


## Input Parameter

- ***funct -*** the function name





## 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.
