SYNOPSIS

#include <netdb.h>

int setrpcent(int stayopen);

DESCRIPTION

setrpcent opens the Sun RPC program numbers file, that is, a file with the same format as /etc/rpc in the UNIX environment. If the file is already open, setrpcent rewinds the file so that succeeding getrpcent calls can read it sequentially. Specifying a nonzero value for stayopen causes the protocols file to remain open between subsequent getrpcbyname and getrpcbynumber calls. Refer to /etc/rpc and Network Administration for information on naming this file for your system.

RETURN VALUE

setrpcent does not return a value.

CAUTION

The value that getrpcbynumber returns points to a static structure within the library. You must copy the information from this structure before you make further getrpcbyname , getrpcbynumber , or getrpcent calls.

PORTABILITY

setrpcent is portable to other systems that support Sun RPC 4.0.

IMPLEMENTATION

This function is built from the Sun RPC 4.0 distribution.
