CHook list_manager Help

[Ajit]

Hi Friends

 

When I try to use the following Function

 

list_manager (TL_ID, tool_library, LSTMGR_GET, &tl_head);

 

I define tl_list *tl_head;

 

error created while compling

 

error C2664: 'void *(unsigned long,char *,short,void ** )' : cannot convert parameter 4 from 'struct _tl_list ** ' to 'void ** '

 

What to do for resolve this error.

 

Thanks in advance.

This function defined in file

C:CHDevM_ASSOC.H is as below

 

// Purpose: retrieve or free COPIES of linked lists of operations, tools or

// material lists from libraries or the current database

#define LSTMGR_GET 0 // get a linked list of operations, tools or matls from databse or library

#define LSTMGR_FREE 1 // free memory from a linked list

EXTERN void * (*_list_manager) (

ulong lib_type, // I: list item type (OP_ID, TL_ID or M_ID)

char *lib_name, // I: library name or "" (null string) for current database

short mode, // I: LSTMGR_GET or LSTMGR_FREE

void **list_ptr); // IO: pointer to alloc'd linked list of items

#define list_manager (*_list_manager)

In my experience with the list_manager() function, I've noticed that when compiling as a C++ program, I get the same compiler error that you do. It hates the fourth paramter. No matter what kind of pointer you try to pass, even a void one, the same error results. But when I complile as a C program, all is fine (except for the fact that I'm stuck using C for that given project).

Works fine for me but I mainly use C. Pointers suck.

 

Off the top of my head does something like this work?

 

list_manager (TL_ID, tool_library, LSTMGR_GET, & (void) tl_head );
