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. //-------------------------------------------------------------------------- #ifndef
