jtc 2d903c854c Changing type of "c" to unsigned did not fix the problem --- a signed
char is sign extended before it is assigned to an unsigned int.  This
fix, which has been tested with a different testcase, adds casts to
signed chars which results in proper behavior.

jtc 83481cc8e8 Changing type of "c" to unsigned did not fix the problem --- a signed
char is sign extended before it is assigned to an unsigned int.  This
fix, which has been tested with a different testcase, adds explicit
casts to unsigned char before the value of a character is copied.

jtc 24de9e4a12 The argument to isfoo() must be representable as an unsigned char, so
type of "c" has been changed to unsigned.  This change allows these
functions will work with strings with their 8th bit set.

jtc 6d8b15101f Install linkaddr.3 as link_addr.3 and link_ntoa.3 too. 1996-07-10 20:15:48 +00:00
thorpej 500e663387 Now that setreuid() and setregid() are system calls again, don't call
the C library "private" versions.  Doing so results in unresolved
symbols the next time a dynamically linked program is run after the
new C library is installed.

thorpej 688ff1ddf9 Correct think-o; this is an assembler source file (and the Makefile
expected as such).

explorer 7e4136b303 Add a continuation slash in the commented-out i387 section 1996-07-05 22:26:51 +00:00
jtc a0d2fe2548 Thanks to the calling conventions used by some cpus, the argument lists
passed to the execl(), execle(), and execlp() functions are in the form
of the argument vector to be passed to execve().  On these architectures,
it is unnecessary to count the number of arguments, allocate space on
the stack, copy the arguments, etc.  The vector already on the stack
can be used instead.

When some arguments are passed in registers (like most RISC CPU's), it
should be possible to allocate stack space adjacent such that the
registers can be copied to that memory.  After that, the same
approach described above can be used.

This change takes advantage of this on the i386, m68k, and ns32k.  It
is probably true on the vax, but I am unable to check.  RISC CPU's
probably need assembly language implementations to ensure everything
is placed exactly as needed when registers are copied to the stack...

jtc a174b58e2c Added a new VA_START macro to hide the differences between varargs.h

jtc b021f209c3 Changed to conform to POSIX.2 B.3.2.2 "popen() shall ensure that any streams
from previous popen() calls that remain open in the parent process are closed

leo fa72190309 Fix the empty error message problem more completely. When the magic-check
fails on the cpu_hdr, return 0 instead of -1. This allows the caller to
distinguise between fatal errors and 'nothing there'.

leo cca068a144 Fix the mysterious empty error message when savecore is executed and no
dump is present. This was caused by the fact that kvm_dump_mkheader() was
called *before* savecore checks the dump magic and kvm_dump_mkheader() returned
-1 without setting an error message. The latter is fixed now.

jtc 3a375fb249 Merged in changes from branch (make sure all memory, file descriptors,

colon.  Try all paths in NLSPATH as per XPG4.2.  Expand %l, %t, and %c

jtc 0df251764e Changed clnt_{s,}p{errno,error,createerror} so that the functions that
output emit newlines and those that return a pointer to string do not
append them.

The existing behavior was inherited from RPC4.0, but this seems to have
been corrected sometime before SunOS 4.1.

The documentation has been updated to reflect the new behavior.

christos 1d4349e7c8 ypset(8) stopped working; reason:
xdr_ypbind_setdom() would always fail because the test for
xdr_ypdomain_wrap_string() was reversed. Fixed this and in
the process made all the function tests to be of the form:

	if (!xdr_foo())
		return FALSE;
	....
	return TRUE;

instead of having some of them like above and others like:
	if (xdr_foo() == FALSE)
		return FALSE;
	...

	return xdr_bar();

this is more consistant now and hopefully in the future people
will pattern match correctly and not introduce spurious errors.

cgd 0396d19a02 use p->hashfraction when doing non-time-critical calculations, rather than
using HASHFRACTION directly.  in time-critical calculations, if HASHFRACTION
is a power of two, check that p->hashfraction == HASHFRACTION and if so do
the calculation with the compiled-in value so that the compiler can optimize
out (potentially) expensive divisions.  if p->hashfraction != HASHFRACTION,
actually do the division.  This has the result that on machines with slow
division, the division can be optimized out of the common case, but that
if HASHFRACTION changes from the compiled-in value (for whatever reason),
profiling will still work.  Changes suggested by Chris Torek.

jtc 8e1fdaa50e Don't special case shift counts > QUAD_BITS or == 0. The former is
undefined behavior (so we can do whatever we want) while the latter
doesn't happen much in actual practice.

These changes make these functions considerably smaller and faster.
