renamed some flags for consistency obey casing rules for symbol names ( case sensitive for unix like ) deleted the setenv code proper stacking of symbols values some non symbols related mods ( cosmetics ??? ) tested on ... Yosemite(CLANG), Centos-6(GCC), Centos-7 (CLANG and GCC) ( reinstalling windows XP under VMware takes longer than planned )

// This header file #included by 'featall.h' and 'hercules.h'

|
/*
|
|
All HOST-operating-specific (Win32, Apple. Linux, etc) FEATures
|
|
and OPTIONs that cannot be otherwise determined via configure.ac
|
|
tests should be #defined here, and ONLY here!
|
|
|
|
-----------------------------------------------------------------
|
|
REMINDER: please do NOT use host-specific tests anywhere else in
|
|
Hercules source code if you can help it! (e.g. #ifdef WIN32, etc)
|
|
|
|
Instead, add a test to configure.ac which tests for the availability
|
|
of the specific feature in question and then #defines a OPTION_XXX
|
|
which can then be used in Hercules source code.
|
|
-----------------------------------------------------------------
|
|
|
|
The ONLY allowed exception is in the Hercules.h and htypes.h
|
|
header files where different header files need to be #included
|
|
(e.g. sockets) and/or typedef/#defines need to be made depending
|
|
on the host build system type.
|
|
|
|
ONLY IF such a configure.ac test is impractical or otherwise not
|
|
possible should you then hard-code the OPTION_XXX setting here in
|
|
this member (and ONLY in this member!) depending on the host o/s.
|
|
|
|
Thus, all of the below hard-coded options are candidates for some
|
|
future configure.ac test.
|
|
|
|
Feel free to design one.
|
|
|
|
Please. :)

'OPTION_SCSI_ERASE_TAPE'
|
|
'OPTION_SCSI_ERASE_GAP'
|
|
|
|
NOTE: The following SHOULD in reality be some sort of test
|
|
within configure.ac, but until we can devise some sort of
|
|
simple configure test, we must hard-code them for now.
|
|
|
|
According to the only docs I could find:
|
|
|
|
MTERASE Erase the media from current position.
|
|
If the field mt_count is nonzero, a full
|
|
erase is done (from current position to
|
|
end of media). If mt_count is zero, only
|
|
an erase gap is written. It is hard to
|
|
say which drives support only one but not
|
|
the other option
|
|
|
|
HOWEVER, since it's hard to say which drivers support short
|
|
erase-gaps and which support erase-tape (and HOW they support
|
|
them if they do! For example, Cygwin is currently coded to
|
|
perform whichever type of erase the drive happens to support;
|
|
e.g. if you try to do an erase-gap but the drive doesn't support
|
|
short erases, it will end up doing a LONG erase [of the entire
|
|
tape]!! (and vice-versa: doing a long erase-tape on a drive
|
|
that doesn't support it will cause [Cygwin] to do an erase-
|
|
gap instead)).
|
|
|
|
THUS, the SAFEST thing to do is to simply treat all "erases",
|
|
whether short or long, as 'nop's for now (in order to prevent
|
|
the accidental erasure of an entire tape!) Once we happen to
|
|
know for DAMN SURE that a particular host o/s ALWAYS does what
|
|
we want it to should we then change the below #defines. (and
|
|
like I said, they really SHOULD be in some type of configure
|
|
test/setting and not here).

File name comparisons
|
|
('strcmp' vs. 'strcasecmp')
|
|
|
|
On Windows, file names are not case sensitive. While the case
|
|
of the file name may be preserved by the file system (and thus
|
|
show file names in both upper/lower case in directory listings
|
|
for example), the file system itself is NOT case-sensitive. File
|
|
names "Foo", "foo", "fOo", "FoO", etc, all refer to the same file.
|
|
|
|
On other platforms however (e.g. *nix), the file system IS case
|
|
sensitive. File names "Foo", "foo", "fOo", "FoO", etc, all refer
|
|
to different files on such systems. Thus we define a 'strfilecmp'
|
|
macro to be used for filename comparisons and define it to be
|
|
strcasecmp on Win32 platforms and strcmp for other platforms.
