NAME

       rpc - Remote procedure call file

DESCRIPTION

       The rpc file is an ASCII file that contains the following information:

       rpc name
       numerical rpc ID
       aliases

       Each  rpc  name is separated from the next by a new line.  Items are separated by any number of blanks or tab characters or both.  A number
       sign (#) indicates the beginning of a comment; characters up to the end of the line are not interpreted by routines that search the file.

       The rpc database can be distributed in a network by a naming service, such as Network Information Service (NIS) or BIND.  See  the  Network
       Administration for setup information.

NAME

       getrpcent, getrpcbynumber, getrpcbyname, setrpcent, endrpcent - Get rpc entry

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include </rpc/netdb.h>
       struct rpcent *getrpcent(void);

       struct rpcent *getrpcbynumber(
	       int number);

       struct rpcent *getrpcbyname(
	       char *name);

       void setrpcent(
	       int stayopen);

       void endrpcent(void);

DESCRIPTION

       The  getrpcent,	getrpcbynumber and getrpcbyname functions return pointers to an object with the following structure containing the broken-
       out fields of a line in the rpc database: struct  rpcent {		/* see getrpcent(3) */
	       char    *r_name;
	       char    **r_aliases;   /* alias list */
	       int     r_number;      /* rpc program number */ }; struct group *getrpcent(), *getrpcbynumber(), *getrpcbyname();

       The members of this structure are:

       r_name	  The name of the rpc.
       r_aliases A zero-terminated list of alternate names for the rpc.
       r_number   The rpc program number for the rpc.

       If the stayopen flag on the setrpcent subroutine is null, the rpc database is opened.  Otherwise the setrpcent has the effect of  rewinding
       the rpc database.  The endrpcent may be called to close the rpc file when processing is complete.

       The  getrpcent subroutine simply reads the next line while getrpcbynumber and getrpcbyname search until a matching gid or name is found (or
       until EOF is encountered).  The getrpcent subroutine keeps a pointer in the database, allowing successive calls to be used  to  search  the
       entire file.

       A call to setrpcent must be made before a while loop using getrpcent in order to perform initialization and an endrpcent must be used after
       the loop.  Both getrpcbynumber and getrpcbyname make calls to setrpcent and endrpcent.

NOTES

       The getrpcent(), getrpcbynumber(), and getrpcbyname() functions return pointers to thread-specific data.  Subsequent calls to  these  func-
       tions from the same thread overwrite this data.

       If NIS (formerly YP) is running, getrpcent does not return the entries in any particular order. See the Network Administration for NIS set-
       up information.

       The rpc information is stored locally in /etc/rpc or is distributed by NIS, or both.  To determine which file or files to  search,  and	in
       which order, the system uses the switches in the /etc/svc.conf file.

RETURN VALUES

       A null pointer (0) is returned on EOF or error.
