Detailed Description

Port database for sockets.

The port database provides a functionality for registering, allocating, and freeing ports.

Function Documentation

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.

Parameters

[out] p_port Pointer to a variable where the allocated port number should be stored.

Return values

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.

Parameters

[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.

Parameters

max_len The max length of the portdb.

Return values

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.

Parameters

[in] port The port to mark as in use.

Return values

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.
