descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.
the first two items result in the addition of code similar to the
following in various functions:
_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif
source has been exhausted. this allows getgrent() across multiple
sources (e.g, ``group: files nis'') to work correctly. the flags are
reset in setgrent()/endgrent().
(as per similar change in getpwent.c rev 1.42)
XXX: this change means that code that uses getgrent() to obtain a list
of groups will have to do duplicate suppression... getgrouplist()
springs to mind; i'm about to modify that
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.
This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
to the null pointer before invocation, so that the test in the
error case of "if (outdata != NULL) free(outdata)" won't potentially
try and free memory that wasn't malloc()ed.
* factor some duplicated code out of both parts of an "if {} else {}"
construct.
* remove use of `register' & KNFify.
