PetscStackUpdateLine#
in a function that has a PetscFunctionBegin or PetscFunctionBeginUser updates the stack line number to the current line number.
Synopsis#
#include <petscsys.h>
void PetscStackUpdateLine
Not Collective
Notes#
Using PetscCall() and friends automatically handles this process
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.
With thread safety enabled, this variable has a separate instance for each thread.
This is used by PetscCall() and is otherwise not like to be needed
