* nss/nss_files/files-service.c (getservbyname): Take second arg PROTO
and check it.
* nss/nss_files/files-XXX.c: Comment fix.
Fri Jul 12 01:28:35 1996 Ulrich Drepper <drepper@cygnus.com>
* nss/getXXent_r.c (GETFUNC_NAME_STRING): Define with name
of reentrant function.
(setup): Pass additional argument with function name we are
looking for.
(SETFUNC_NAME, ENDFUNC_NAME, GETFUNC_NAME): Call setup with
new argument {SET,END,GET}FUNC_NAME_STRING.
* nss/getXXent.c (GETFUNC_NAME): RESULT must be static because
we return a pointer.
Thu Jul 11 18:20:44 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* nss/nss_files/files-parse.c: Add comment about things to #define.
* nss/nss_files/files-hosts.c (NEED_H_ERRNO): Define it.
* nss/nss_files/files-parse.c (STRING_FIELD): Don't flag NUL before
terminator char as an error.
* nss/getXXbyYY_r.c (REENTRANT_NAME): Set *H_ERRNOP, not h_errno.
Thu Jul 11 03:21:10 1996 Ulrich Drepper <drepper@cygnus.com>
* catgets/gencat.c (write_out): Move code to determine new
best size out of inner loop.

(endmntent): Return 1 one success, 0 on failure.
(getmntent): Chop newline and ignore empty lines.
Mon Jul 8 21:18:40 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>

|
|
|* *|
|
|
|* LOOKUP_TYPE - the return type of the function *|
|
|
|* *|
|
|
|* FUNCTION_NAME - name of the non-reentrant function *|
|
|
|* *|
|
|
|* DATABASE_NAME - name of the database the function accesses *|
|

|* (e.g., host, services, ...) *|
|

|* *|
|
|
|* ADD_PARAMS - additional parameter, can vary in number *|
|
|

|* ADD_VARIABLES - names of additional parameter *|
|
|
|* *|
|
|
|* Optionally the following vars can be defined: *|

|* the global `h_errno' variable. *|

|
|
|* NEED__RES - the global _res variable might be used so we *|
