How to pass variable function pointer arguments to a function in C

Question

I have a function that performs a search over elements of a mesh. I want that function to be able to call a variety of other functions to have them perform different actions over the mesh. For that purpose, is it possible to define a variable argument list where the variable arguments are all function pointers (all of the same "signature")? The variable function arguments are of the form:

int(*function)(struct mesh*, void*,int)

Here's a draft of what I thought could work (NOTE AppCtx is a struct, and num is the number of function arguments). My idea is to declare a function pointer of the above "signature" and then loop through the va_list's arguments. As I loop through these arguments I want the pointer thing to point to the different functions given to SearchFunction by means of the ....

#include <stdarg.h>
int SearchFunction(struct mesh,int depth,void* AppCtx,int num,...){
  va_list valist;
  int ii,jj, *Start,*End;
  va_start(valist, num);
 int (struct mesh*, void*,int) *thing; //Is this allowed?
  switch(depth){
    case 0:
      Start = &(mesh->LV0); End = &(mesh->LVN);
      break;
    case 1:
      Start = &(mesh->LE0); End = &(mesh->LEN);
      break;
    case 2:
      Start = &(mesh->LF0); End = &(mesh->LFN);
      break;
    case 3:
      Start = &(mesh->LC0); End = &(mesh->LCN);
      break;
  }//end switch.

/* access all the arguments assigned to valist */
  for (ii = 0; ii < num; ii++) {
    action[ii] = va_arg(valist, int (struct mesh*, void*,int)); //Is this allowed?
  }//end "ii" loop.
  for(ii = *Start;ii < *End;ii++){
    for(jj = 0; jj < num;jj++){
      thing = action[jj]; //Is this allowed?
      mesh->ierr = thing(mesh,AppCtx,ii); CHKERRQ(mesh->ierr); //Here I attempt to call the functions.
    }//end "jj" loop.
  }//end "ii" loop.
/* clean memory reserved for valist */
va_end(valist);
return mesh->ierr;
}
