+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.

+.SH NAME
+endhostent,
+gethostent,
+sethostent
+\(em network host database functions
+.SH SYNOPSIS
+.LP
+.nf
+#include <netdb.h>
+.P
+void endhostent(void);
+struct hostent *gethostent(void);
+void sethostent(int \fIstayopen\fP);
+.fi
+.SH DESCRIPTION
+These functions shall retrieve information about hosts. This
+information is considered to be stored in a database that can be
+accessed sequentially or randomly. The implementation of this database
+is unspecified.
+.TP 10
+.BR Note:
+In many cases this database is implemented by the Domain Name System,
+as documented in RFC\ 1034, RFC\ 1035, and RFC\ 1886.
+.P
+.P
+The
+\fIsethostent\fR()
+function shall open a connection to the database and set the next entry
+for retrieval to the first entry in the database. If the
+.IR stayopen
+argument is non-zero, the connection shall not be closed by a call to
+\fIgethostent\fR(),
+and the implementation may maintain an open file descriptor.
+.P
+The
+\fIgethostent\fR()
+function shall read the next entry in the database, opening and closing
+a connection to the database as necessary.
+.P
+Entries shall be returned in
+.BR hostent
+structures.
+.P
+The
+\fIendhostent\fR()
+function shall close the connection to the database, releasing any open
+file descriptor.
+.P
+These functions need not be thread-safe.
+.SH "RETURN VALUE"
+Upon successful completion, the
+\fIgethostent\fR()
+function shall return a pointer to a
+.BR hostent
+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.
+.P
+The application shall not modify the structure to which the return
+value points, nor any storage areas pointed to by pointers within the
+structure. The returned pointer, and pointers within the structure,
+might be invalidated or the structure or the storage areas might be
+overwritten by a subsequent call to
+\fIgethostent\fR().
+The returned pointer, and pointers within the structure, might also
+be invalidated if the calling thread is terminated.
+.SH ERRORS
+No errors are defined for
+\fIendhostent\fR(),
+\fIgethostent\fR(),
+and
+\fIsethostent\fR().
