dmp_del (cdt_func_ptr) struct cdt * ( (*cdt_func_ptr) ( ));
| cdt_func_ptr | Specifies a function that returns a pointer to a component dump table. The function and the component dump table must both reside in pinned global memory. |
Kernel extensions use the dmp_del kernel service to unregister data areas previously registered for inclusion in a system dump. A kernel extension that uses the dmp_add service to register such a data area can use the dmp_del service to remove this entry from the master dump table.
The dmp_del kernel service can be called from the process environment only.
| 0 | Indicates a successful operation. |
| -1 | Indicates that the function pointer to be deleted is not in the master dump table. |
The dmp_del kernel service is part of Base Operating System (BOS) Runtime.
