:orphan: # PetscStackPopNoCheck Pops a function name from the PETSc default stack that tracks where the running program is currently in the source code. ## Synopsis ``` #include void PetscStackPopNoCheck(char *funct); ``` Not Collective ## Input Parameter - ***funct -*** the function name ## Notes Using `PetscCall()`, `PetscCallExternal()`, `PetscCallBack()` and friends negates the need to call this 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. ## Developer Note `PetscStackPopNoCheck()` takes a function argument while `PetscStackPop` does not, this difference is likely just historical. ## See Also `PetscAttachDebugger()`, `PetscStackCopy()`, `PetscStackView()`, `PetscStackPushNoCheck()`, `PetscStackPop` ## Level developer ## Location include/petscerror.h --- [Edit on GitLab](https://gitlab.com/petsc/petsc/-/edit/release/include/petscerror.h) [Index of all Sys routines](index.md) [Table of Contents for all manual pages](/manualpages/index.md) [Index of all manual pages](/manualpages/singleindex.md)
