- The functions map interface index to readable interface name (such as
- "lo0"), and vice versa.
-
- _i_f__i_n_d_e_x_t_o_n_a_m_e converts interface index to readable interface name. The
- _i_f_n_a_m_e argument must point to a buffer of at least IF_NAMESIZE bytes into
- which the interface name corresponding to the specified index is
- returned. (IF_NAMESIZE is also defined in <net/if.h> and its value
- includes a terminating null byte at the end of the interface name.) This
- pointer is also the return value of the function. If there is no
- interface corresponding to the specified index, NULL is returned and
- errno is set to ENXIO. If there was a system error (such as running out
- of memory), errno is set to ENOMEM.
-
- _i_f__n_a_m_e_t_o_i_n_d_e_x converts readable interface name to interface index
- positive integer value. If the specified interface does not exist, 0
- will be returned.
-
- _i_f__n_a_m_e_i_n_d_e_x returns an array of _i_f__n_a_m_e_i_n_d_e_x structures. _i_f__n_a_m_e_i_n_d_e_x
- is also defined in <net/if.h>, and is as follows:
-
- struct if_nameindex {
- unsigned int if_index; /* 1, 2, ... */
- char *if_name; /* null terminated name: "le0",.. */
- };
-
-
- The end of the array of structures is indicated by a structure with an
- _i_f__i_n_d_e_x of 0 and an _i_f__n_a_m_e of NULL . The function returns a NULL
- pointer upon an error and errno is set to the approprate value. The
- memory used for this array of structures along with the interface names
- pointed to by the _i_f__n_a_m_e members is obtained dynamically. This memory
- is freed by the _i_f__f_r_e_e_n_a_m_e_i_n_d_e_x function.

- _i_f__f_r_e_e_n_a_m_e_i_n_d_e_x takes a pointer that was returned by _i_f__n_a_m_e_i_n_d_e_x as
- argument (_p_t_r), and it reclaims the region allocated.

- _i_f__n_a_m_e_t_o_i_n_d_e_x returns 0 on error, positive integer on success.
- _i_f__i_n_d_e_x_t_o_n_a_m_e and _i_f__n_a_m_e_i_n_d_e_x return NULL on errors.
