-.SH DESCRIPTION
-The
-.BR getrpcent_r (),
-.BR getrpcbyname_r (),
-and
-.BR getrpcbynumber_r ()
-functions are the reentrant equivalents of, respectively,
-.BR getrpcent (3),
-.BR getrpcbyname (3),
-and
-.BR getrpcbynumber (3).
-They differ in the way that the
-.I rpcent
-structure is returned,
-and in the function calling signature and return value.
-This manual page describes just the differences from
-the nonreentrant functions.
-
-Instead of returning a pointer to a statically allocated
-.I rpcent
-structure as the function result,
-these functions copy the structure into the location pointed to by
-.IR result_buf .
-
-The
-.I buf
-array is used to store the string fields pointed to by the returned
-.I rpcent
-structure.
-(The nonreentrant functions allocate these strings in static storage.)
-The size of this array is specified in
-.IR buflen .
-If
-.I buf
-is too small, the call fails with the error
-.BR ERANGE ,
-and the caller must try again with a larger buffer.
-(A buffer of length 1024 bytes should be sufficient for most applications.)
-.\" I can find no information on the required/recommended buffer size;
-.\" the nonreentrant functions use a 1024 byte buffer -- mtk.
-
-If the function call successfully obtains an RPC record, then
-.I *result
-is set pointing to
-.IR result_buf ;
-otherwise,
-.I *result
-is set to NULL.
-.SH RETURN VALUE
-On success, these functions return 0.
-On error, they return one of the positive error numbers listed in ERRORS.
-
-On error, record not found
-.RB ( getrpcbyname_r (),
-.BR getrpcbynumber_r ()),
-or end of input
-.RB ( getrpcent_r ())
-.I result
-is set to NULL.
-.SH ERRORS
-.TP
-.B ENOENT
-.RB ( getrpcent_r ())
-No more records in database.
-.TP
-.B ERANGE
-.I buf
-is too small.
-Try again with a larger buffer
-(and increased
-.IR buflen ).
-.SH CONFORMING TO
-These functions are GNU extensions.
-Functions with similar names exist on some other systems,
-though typically with different calling signatures.
-.SH SEE ALSO
-.BR getrpcent (3),
-.BR rpc (5)

-.I man-pages
-project.
