—
get RPC entry
SYNOPSIS¶
#include
<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¶
Thegetrpcent
(),
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 */ };
- 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.
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.
FILES¶
- /etc/rpc
