        typedef void* NUTCLIENT_t;

        void nutclient_destroy(NUTCLIENT_t client);

        typedef char** strarr;

        strarr strarr_alloc(unsigned short count);

        void strarr_free(strarr arr);

DESCRIPTION

The nutclient_destroy() function destroys a NUTCLIENT_t or derived (like NUTCLIENT_TCP_t) connection object, and frees allocated memory.

  • The strarr type represents an array of C strings (array of char pointer). The array must always be terminated by a NULL pointer.

    Pointed strings must be allocated by (x)calloc or (x)strdup.

  • The strarr_alloc() function allocates a strarr array with the specified number of (non-initialized) string pointers.

    Another additional pointer set to NULL is added at the end of the array.

  • The strarr_free function frees a strarr array. It also frees all pointed strings.

Common arguments:

  • dev is the device name.
