Defect Description:
PHCO_26111:
The h_errno() function is mangled up and hence
linking in C++ environment fails. The function name
encoding in C++ changes the name of the API in the
application. Hence at link time the right symbol is
not recognized and a linker error is flagged.
Resolution:
The h_errno() has been protected by the extern "C"
declaration. This tells the C++ compiler not to follow
function name encoding and hence mangling does not occur.
C type of compilation is followed in the case of h_errno().
JAGab13405; SR 8606112945
PHCO_23963:
The getres() function is mangled up and hence linking in
cplusplus environment fails. The function name encoding in
cplusplus changes the name of the API in the application.
Hence at link time the right symbol is not recognised and a
linker error is flagged.
Resolution:
The getres() has been protected by the extern "C"
declaration. This tells the c++ compiler not to follow
function name encoding and hence mangling does not occur. C
type of compilation is followed in the case of getres().
JAGad52748; SR 8606183535
ctype.h has obsolete compiler defines that should be
removed.
Resolution:
The following obsolete #defines are removed from ctype.h:
/* The following character class constants are obsolete: */
# define _U 01
# define _L 02
# define _N 04
# define _S 010
# define _P 020
# define _C 040
# define _B 0100
# define _X 0200
# define _A 01
# define _G 02
# define _PR 04
The above definitions are obsoleted since 10.x.
Fully Supported symbols insted of the above obsolete symbols
are given below.
Obsolete symbol Supported Symbol
--------------- ----------------
_U _ISALPHA
_L _ISALNUM
_N _ISBLANK
_S _ISCNTRL
_P _ISDIGIT
_C _ISGRAPH
_B _ISLOWER
_X _ISPRINT
_A _ISALPHA
_G _ISALNUM
_PR _ISBLANK
JAGad47817; SR 8606178590
PHCO_23092:
gettimeofday is very slow for certain vendors who use it for
time stamping because it calls a heavy weight system call to
get the current time of the day.
Resolution:
A new API hrtime_t gethrtime(void) has been added to libc.
Declaration for this API is added in the header file
/usr/include/time.h
JAGad44410; SR 8606175166
PHCO_21017:
Put all STL (Standard C++-library) classes in
namespace std::, because it is the standard.
Resolution:
The libc header files that are part of the C++ standard
language definition are modified to support the namespace
std:: standard
JAGaa86632; SR 1653275354
#include <cwchar>
int main () {}
Try the above test with
% aCC -AA t.c -E -.i
on a 11.00 system. The generated t.i will have a bunch
of declarations that should not be there.
In some cases, several headers like stdio.h should be
included from /usr/include instead of /opt/aCC/include.
When this happens, these headers should not be included
from /opt/aCC/include.
The -I order for aCC always searchs /opt/aCC/include
first. For HP 11.x version of /usr/include/wchar.h,
it has
# include <ctype.h> /* _U, _L, etc */
# include <stddef.h> /* NULL, size_t, etc */
# include <stdio.h> /* stdio prototypes */
# include <stdlib.h> /* multibyte prototypes */
# include <time.h> /* tm struct */
without include guard. That will lead to /opt/aCC/ctype.h
getting included.
Resolution:
The preinclude guard as appeared in HP 10.20 version
should be there always.
The 10.20 has the following:
/* preinclude guards needed for aC++ namespace std */
#ifndef _CTYPE_INCLUDED
# include <ctype.h> /* _U, _L, etc */
#endif
#ifndef _STDDEF_INCLUDED
# include <stddef.h> /* NULL, size_t, etc */
#endif
#ifndef _STDIO_INCLUDED
# include <stdio.h> /* stdio prototypes */
#endif
#ifndef _STDLIB_INCLUDED
# include <stdlib.h> /* multibyte prototypes */
#endif
#ifndef _TIME_INCLUDED
# include <time.h> /* tm struct */
#endif
JAGac88525; SR 8606129620
PHCO_18229:
This deadlock is due to excessive locking of /etc/mnttab
in the getmntent(3X) family of APIs. The /etc/mnttab
access policies have been changed to no longer require
read locking. setmntent(3X) still tries to acquire a
write lock when opening /etc/mnttab for writing/updating.
In the libc patch, setmntent(3X) no longer uses a read
lock when opening the mnttab file, and a new API,
delmntent(3X) has been developed. This patch is required
for developers intending on using the new API, delmntent,
implemented in libc.2 patch PHCO_18227.
Resolution:
The problem was caused by excessive locking of /etc/mnttab
in the getmntent(3X) family of APIs, and by incorrect use
of the getmntent(3X) APIs by commands such as mount(1M)
and umount(1M). In the patch, setmntent(3X) no longer uses
a read lock when opening the mnttab file, and a new API,
delmntent(3X), has been developed for use by commands that
delete entries from the mnttab file. Use of this patch
will avoid a possible deadlock situation during concurrent
invocations of mount(1M) or other commands that write to
or read from /etc/mnttab.

PHCO_17078:
Files /usr/include/threads/rec_mutex.h and
/usr/include/threads/ktepv.h, included with PHCO_14705
are now obsolete.
JAGaa21913
PHCO_15769:
The CONCAT macro in <inttypes.h> returns an incorrect
value in C++ applications. JAGaa00515.
PHCO_14705:
Enhancement request for providing a new threads API
__thread_detach(). The following header files are added:
/threads/rec_mutex.h, /threads/ktepv.h
JAGaa01380
While supplying the prototype for get_expiration_time,
<time.h> does not take care of the condition where
_INCLUDE_HPUX_SOURCE flag is defined during compile
time. Hence prototype for the get_expiration_time() API
is not visible if _INCLUDE_HPUX_SOURCE is defined while
building applications. JAGaa01500
PHCO_14224:
C++ applications do not have access to 64-bit data types
and Large Files interfaces when compiled in 32-bit mode.
JAGaa00365, JAGaa01298, JAGaa01113, SR 1653208348.
PHCO_14103:
To enable large malloc feature for malloc(3C).
Enhancement:
No (superseded patches contained enhancements)
PHCO_23963:
Enhancements were delivered in this patch or one it has
replaced. Please review the Defect Description text for
