Port database for sockets.
The port database provides a functionality for registering, allocating, and freeing ports.
| uint32_t portdb_alloc | ( | uint16_t * | p_port | ) |
Function for allocating a port.
Looks for an available port in the database and allocates it to the caller.
| [out] | p_port | Pointer to a variable where the allocated port number should be stored. |
| NRF_SUCCESS | If a free port was located and successfully allocated. |
| SOCKET_NO_AVAILABLE_PORTS | If no available ports were found. |
| void portdb_deinit | ( | void | ) |
Function for deinitializing the portdb.
This will free all memory allocated by this portdb.
| void portdb_free | ( | uint16_t | port | ) |
Function for freeing a port.
Mark a given port as free and make it available for others to register or allocate.
| [in] | port | The port to mark as free. |
| uint32_t portdb_init | ( | uint32_t | max_len | ) |
Function for initializing the port database.
This must be called before allocating and freeing ports.
| max_len | The max length of the portdb. |
| NRF_SUCCESS | If successfully initialized. |
| uint32_t portdb_register | ( | uint16_t | port | ) |
Function for registering a port.
Marks a given port in the database as being in use.
| [in] | port | The port to mark as in use. |
| NRF_SUCCESS | If port was successfully marked as in use. |
| SOCKET_NO_AVAILABLE_PORTS | If there was no slot in which to register the port. |
| SOCKET_PORT_IN_USE | If the port has already been registered or allocated. |
