Gets a host file entry from the network host database file.
#include <netdb.h> struct hostent *gethostent (void);
See the <netdb.h> header file for a description of the hostent structure.
This routine uses a common static area for its return values. Therefore, subsequent calls to this routine overwrite any existing network entry. You must make a copy of the network services entry, if you wish to save it.
| x | A pointer to the hostent structure. |
| NULL | Indicates an error. |
