PetscVoidFn

A prototype of a void fn(void) function

Synopsis

PETSC_EXTERN_TYPEDEF typedef void PetscVoidFn(void);

Notes

PetscVoidFn * plays the role of void * for function pointers in the PETSc API that do not return an error code. It is used where a function pointer is needed but it is not possible to use the full prototype of the function.

PetscErrorCodeFn is similar to PetscVoidFn but should be used when the function returns a PetscErrorCode

The deprecated PetscVoidFunction works as a replacement for PetscVoidFn *.

The deprecated PetscVoidStarFunction works as a replacement for PetscVoidFn **.
