LEARN ABOUT POSIX
getnetent
ENDNETENT(P) POSIX Programmer's Manual ENDNETENT(P)
NAME
endnetent, getnetbyaddr, getnetbyname, getnetent, setnetent - network database functions
SYNOPSIS
#include <netdb.h>
void endnetent(void);
struct netent *getnetbyaddr(uint32_t net, int type);
struct netent *getnetbyname(const char *name);
struct netent *getnetent(void);
void setnetent(int stayopen);
DESCRIPTION
These functions shall retrieve information about networks. This information is considered to be stored in a database that can be accessed
sequentially or randomly. The implementation of this database is unspecified.
The setnetent() function shall open and rewind the database. If the stayopen argument is non-zero, the connection to the net database
shall not be closed after each call to getnetent() (either directly, or indirectly through one of the other getnet*() functions), and the
implementation may maintain an open file descriptor to the database.
The getnetent() function shall read the next entry of the database, opening and closing a connection to the database as necessary.
The getnetbyaddr() function shall search the database from the beginning, and find the first entry for which the address family specified
by type matches the n_addrtype member and the network number net matches the n_net member, opening and closing a connection to the database
as necessary. The net argument shall be the network number in host byte order.
The getnetbyname() function shall search the database from the beginning and find the first entry for which the network name specified by
name matches the n_name member, opening and closing a connection to the database as necessary.
The getnetbyaddr(), getnetbyname(), and getnetent() functions shall each return a pointer to a netent structure, the members of which shall
contain the fields of an entry in the network database.
The endnetent() function shall close the database, releasing any open file descriptor.
These functions need not be reentrant. A function that is not required to be reentrant is not required to be thread-safe.
RETURN VALUE
Upon successful completion, getnetbyaddr(), getnetbyname(), and getnetent() shall return a pointer to a netent structure if the requested
entry was found, and a null pointer if the end of the database was reached or the requested entry was not found. Otherwise, a null pointer
shall be returned.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
The getnetbyaddr(), getnetbyname(), and getnetent() functions may return pointers to static data, which may be overwritten by subsequent
calls to any of these functions.
RATIONALE
None.
FUTURE DIRECTIONS
None.
