Macros and prototypes for the PLplot package. This header file must
be included by all user codes.
Note: some systems allow the Fortran & C namespaces to clobber each
other. So for PLplot to work from Fortran, we do some rather nasty
things to the externally callable C function names. This shouldn't
affect any user programs in C as long as this file is included.

* USING PLplot
*
* To use PLplot from C or C++, it is only necessary to
*
* #include "plplot.h"
*
* This file does all the necessary setup to make PLplot accessible to
* your program as documented in the manual. Additionally, this file
* allows you to request certain behavior by defining certain symbols
* before inclusion. At the moment the only one is:
*
* #define DOUBLE or..
* #define PL_DOUBLE
*
* This causes PLplot to use doubles instead of floats. Use the type
* PLFLT everywhere in your code, and it will always be the right thing.
*
* Note: most of the functions visible here begin with "pl", while all
* of the data types and switches begin with "PL". Eventually everything
* will conform to this rule in order to keep namespace pollution of the
* user code to a minimum. All the PLplot source files actually include
* "plplotP.h", which includes this file as well as all the internally-
* visible declarations, etc.

* SYSTEM IDENTIFICATION
*
* Several systems are supported directly by PLplot. In order to avoid
* confusion, one id macro per system is used. Since different compilers
* may predefine different system id macros, we need to check all the
* possibilities, and then set the one we will be referencing. These are:
*
* __cplusplus Any C++ compiler
* __unix Any Unix-like system
* __hpux Any HP/UX system
* __aix Any AIX system
* __linux Linux for i386
* (others...)

* Base types for PLplot
*
* Only those that are necessary for function prototypes are defined here.
* Notes:
*
* PLINT is typedef'd to a long by default. This is a change from some
* previous versions, where a int was used. However, so long as you have
* used type PLINT for integer array arguments as specified by the API,
* this change will be transparent for you.
*
* short is currently used for device page coordinates, so they are
* bounded by (-32767, 32767). This gives a max resolution of about 3000
* dpi, and improves performance in some areas over using a PLINT.
*
* PLUNICODE should be a 32-bit unsigned integer on all platforms.
* For now, we are using unsigned int for our Linux ix86 unicode experiments,
* but that doesn't guarantee 32 bits exactly on all platforms so this will
* be subject to change.

/*--------------------------------------------------------------------------*\
* BRAINDEAD-ness
*
* Some systems allow the Fortran & C namespaces to clobber each other.
* For PLplot to work from Fortran on these systems, we must name the the
* externally callable C functions something other than their Fortran entry
* names. In order to make this as easy as possible for the casual user,
* yet reversible to those who abhor my solution, I have done the
* following:
*
* The C-language bindings are actually different from those
* described in the manual. Macros are used to convert the
* documented names to the names used in this package. The
* user MUST include plplot.h in order to get the name
* redefinition correct.
*
* Sorry to have to resort to such an ugly kludge, but it is really the
* best way to handle the situation at present. If all available
* compilers offer a way to correct this stupidity, then perhaps we can
* eventually reverse it.
*
* If you feel like screaming at someone (I sure do), please
* direct it at your nearest system vendor who has a braindead shared
* C/Fortran namespace. Some vendors do offer compiler switches that
* change the object names, but then everybody who wants to use the
* package must throw these same switches, leading to no end of trouble.
*
* Note that this definition should not cause any noticable effects except
* when debugging PLplot calls, in which case you will need to remember
* the real function names (same as before but with a 'c_' prepended).
*
* Also, to avoid macro conflicts, the BRAINDEAD part must not be expanded
* in the stub routines.
*
* Aside: the reason why a shared Fortran/C namespace is deserving of the
* BRAINDEAD characterization is that it completely precludes the the kind
* of universal API that is attempted (more or less) with PLplot, without
* Herculean efforts (e.g. remapping all of the C bindings by macros as
* done here). The vendors of such a scheme, in order to allow a SINGLE
* type of argument to be passed transparently between C and Fortran,
* namely, a pointer to a conformable data type, have slammed the door on
* insertion of stub routines to handle the conversions needed for other
* data types. Intelligent linkers could solve this problem, but these are
* not anywhere close to becoming universal. So meanwhile, one must live
* with either stub routines for the inevitable data conversions, or a
* different API. The former is what is used here, but is made far more
* difficult in a braindead shared Fortran/C namespace.
