/* HOSTOPTS.H -- HOST-specific features and options */
/*-------------------------------------------------------------------*/
// $Id$
// 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. :)

/* ZZ FIXME
'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.
