SYNOPSIS
.In rpc/rpc.h struct rpcent * getrpcent void struct rpcent * getrpcbyname "char *name" struct rpcent * getrpcbynumber "int number" void setrpcent "int stayopen" void endrpcent void
DESCRIPTION
The getrpcent, getrpcbyname, and getrpcbynumber functions each return a pointer to an object with the following structure containing the broken-out fields of a line in the rpc program number data base, /etc/rpc:
struct rpcent {
char *r_name; /* name of server for this rpc program */
char **r_aliases; /* alias list */
long r_number; /* rpc program number */
};
The members of this structure are: | r_name | The name of the server for this rpc program. | | r_aliases | | | A zero terminated list of alternate names for the rpc program. | | r_number | The rpc program number for this service. | |
The getrpcent function reads the next line of the file, opening the file if necessary. The setrpcent function opens and rewinds the file. If the stayopen flag is non-zero, the net data base will not be closed after each call to getrpcent (either directly, or indirectly through one of the other "getrpc" calls). The endrpcent function closes the file. The getrpcbyname and getrpcbynumber functions sequentially search from the beginning of the file until a matching rpc program name or program number is found, or until end-of-file is encountered.
