HP-UX 11i Release Notes (December 2000)

Compatibility
Known Compatibility Exceptions from HP-UX 11.0 to 11i
Chapter 12232
Customization of wctype Methods
This change removes the ability to use customized locale methods for
accessing “wctype”, wide character classification, APIs in order to
provide performance improvements. If an application is built for locales
with localedef -m and the method library includes custom functions for
iswalpha(), iswupper(), iswlower(), iswdigit(), iswxdigit(),
iswalnum(), iswspace(), iswpunct(), iswprint(), iswgraph(),
iswcntrl(), wctype(), iswctype(), the application should now
belinked with the method library and call the method functions directly.
System V Message Queues Expanding Beyond Present
64KB Limit
This change alters the message queue data structures to support queues
larger than 64KB. If one application is built to use the larger queues, all
related applications that use the same message queue must be built to
use the larger queues. See “System-V IPC Message Queue Enhancement
(new)” on page 164 for more information.
Maximum Number of Active Processors for
pstat_getdynamic Changed
This change corrects a defect in the pstat_getdynamic interface so it
adheres to the documentation when it reports the number of processors
that are active on a system. Well-behaved applications will not be
affected by this change. Ill-behaved applications may overestimate the
number of processors that are active on the system. Ill-behaved
applications can be corrected to reference the correct field with a simple
code change. See “instant Capacity on Demand (iCOD)” on page 78 for
more information.
Export Filesystem (NFS) Security Defect Correction
This change corrects the NFS implementation so it conforms to industry
practice when exporting a filesystem. Well-behaved applications will not
be affected by this change. Applications that assume that exporting a
symbolic link to a filesystem will result in the symbolic link being
exported, rather than the directory to which the symbolic link points,
will fail that assumption. Shell scripts and administrative processes may
have to be changed to correct the assumption.
