PetscFunctionListAdd#

Given a routine and a string id, saves that routine in the specified registry.

Synopsis#

#include <petscsys.h>
PetscErrorCode PetscFunctionListAdd(PetscFunctionList *flist,const char name[],void (*fptr)(void))

Not Collective

Input Parameters#

  • fl - pointer to function list object

  • name - string to identify routine

  • fptr - function pointer

Notes#

To remove a registered routine, pass in a NULL fptr.

Users who wish to register new classes for use by a particular PETSc component (e.g., SNES) should generally call the registration routine for that particular component (e.g., SNESRegister()) instead of calling PetscFunctionListAdd() directly.
