* include/hbapifs.h
* src/rtl/filesys.c
+ added new C functions for UNIX and DJGPP builds:
int hb_fsPollFD( PHB_POLLFD pPollSet, int iCount,
HB_MAXINT nTimeOut );
int hb_fsCanRead( HB_FHANDLE hFileHandle, HB_MAXINT nTimeOut );
int hb_fsCanWrite( HB_FHANDLE hFileHandle, HB_MAXINT nTimeOut );
These functions should be used instead of select() in C code to hide
low level access to select()/poll() functionality in *nix builds
(they are supported by DJGPP only to simplify existing code common
for DJGPP and *nix builds). Maximum file handle value which can be
used in select() is limited by FD_SETSIZE. Please note that it's
file handle value not number of file handles in the set. It creates
serious problem for applications which operate on great number of
handles (i.e. servers which have to keep open many sockets, pipes,
files, etc. for their clients) so the new file/socket/pipe/...
handle value can easy exceed FD_SETSIZE limit and in such case
cannot be used with select(). The modification on
2016-04-05 21:24 UTC+0200 Przemyslaw Czerpak
resolved the problem only for sockets and pipes in code which uses
corresponding hb_socket*() and hb_fsPipe*() API but not for all
other cases. This one is for POSIX compilant code which needs pure
POSIX select()/poll() functionality.
Please note that HB_POLLFD structure should is compatible with
struct pollfd defined by POSIX.1-2001 anyhow not all platforms
confirm this standard so portable Harbour code should always use
HB_POLLFD and HB_POLL* constant values instead of POLL* ones.
* include/hbdate.h
* src/common/hbdate.c
+ added new C functions to calculate timeouts:
HB_MAXUINT hb_timerGet( void );
HB_MAXUINT hb_timerInit( HB_MAXINT nTimeOut );
HB_MAXINT hb_timerTest( HB_MAXINT nTimeOut, HB_MAXUINT * pnTimer );
They are designed to be used instead of direct access to
hb_dateMilliSeconds(). Now they internally use hb_dateMilliSeconds()
but it can be easy replaced by any other system monotonic clock by
one local modification inside hb_timerGet() function.
* src/rtl/filesys.c
* use hb_timer*() functions instead of hb_dateMilliSeconds()
* use hb_fsCanRead()/hb_fsCanWrite() instead of select()/poll()
It also fixed timeout processing inside hb_fsPipeIsData() and
hb_fsPipeWrite() in builds using poll()
