| obj | - the PETSc object; this must be cast with a (PetscObject), for example, PetscObjectCompose((PetscObject)mat,...); | |

PetscErrorCode PetscObjectComposeFunctionDynamic(PetscObject obj,const char name[],const char fname[],void *ptr)
PetscObjectComposeFunctionDynamic() can be used with any PETSc object (such as Mat, Vec, KSP, SNES, etc.) or any user-provided object.
The composed function must be wrapped in a EXTERN_C_BEGIN/END for this to work in C++/complex with dynamic link libraries (config/configure.py options --with-shared --with-dynamic) enabled.
