If the .I stayopen flag is non-zero, the net data base will not be closed after each call to .I getrpcent (either directly, or indirectly through one of the other \*(lqgetrpc\*(rq calls). .PP .I Endrpcent closes the file. .PP .I Getrpcbyname and .I getrpcbynumber sequentially search from the beginning of the file until a matching rpc program name or program number is found, or until EOF is encountered. .SH FILES .nf /etc/rpc .RI /etc/yp/ domainname /rpc.bynumber .fi .SH "SEE ALSO" rpc(5), rpcinfo(8), ypservices(8) .SH DIAGNOSTICS Null pointer (0) returned on EOF or error. .SH BUGS All information is contained in a static area so it must be copied if it is to be saved.
