OSS Library Calls (g - h) getnetbyaddr_r(3)
The structure of type netent is defined in the netdb.h header file as:
struct netent {
char *n_name;
char **n_aliases;
int n_addrtype;
uint32_t n_net;
};
The fields of this structure are:
n_name Points to the official name of the network.
n_aliases Points to an array of null-terminated pointers to the alternate names for the
network..mc
n_addrtype The type of network number being returned. Its value is always AF_INET, which
indicates that this is the network potion of an Internet address.
n_net Is the network number, in host order.
ERRORS
If this condition occurs, the getnetbyaddr_r( ) function sets errno to the corresponding value:
[ERANGE] Insufficient storage was supplied via buffer and buflen to contain the data to be
referenced by the resulting netent structure.
FILES
/etc/networks The Internet network name database file.
