/* The optional "long filename" support available with some MSDOS compiler
|

|
* environments running under VFAT systems (Win95) is controlled with the
|
||
|
|
* help of the two preprocessor symbols USE_VFAT and USE_LFN:
|
||
|
|
* - USE_VFAT is a compile time switch that selects the long filename
|
||
|
|
* semantics in mapname()
|
||
|
|
* - USE_LFN is a macro equating to a boolean expression indicating
|
||
|
|
* whether long filenames are supported. If available, this
|
||
|
|
* macro should make use of a runtime function checking the
|
||
|
|
* LFN support.
|
||
|
|
*
|
||
|
|
* The code in msdos.c distinguishes three cases:
|
||
|
|
* 1.) USE_VFAT is not defined:
|
||
|
|
* No support of LFN is included; filenames are mapped to 8+3 plain FAT
|
||
|
|
* syntax unconditionally.
|
||
|
|
* This is achieved by ``#define MAYBE_PLAIN_FAT'' to include the plain
|
||
|
|
* FAT name mapping code and by ``#undef USE_LFN'' to disable bypassing
|
||
|
|
* of the FAT mapping at runtime.
|
||
|
|
* 2.) USE_VFAT is defined:
|
||
|
|
* Support for LFN is enabled.
|
||
|
|
* a) USE_LFN is undefined:
|
||
|
|
* There is no (runtime) check available to distinguish between OS
|
||
|
|
* environments that support VFAT extensions and those that do not.
|
||
|
|
* In this case, filenames are mapped to the more liberal VFAT LFN
|
||
|
|
* syntax unconditionally. The internal switch MAYBE_PLAIN_FAT remains
|
||
|
|
* undefined to exclude to "map to plain FAT" code parts.
|
||
|
|
* b) USE_LFN is defined (hopefully to a boolean runtime LFN check function):
|
||
|
|
* "#define MAYBE_PLAIN_FAT" is applied to include the plain FAT mapping
|
||
|
|
* code; the programs checks at runtime whether the OS supports LFN and
|
||
|
|
* uses the appropiate mapping syntax.
|
||
|

*/

|
||
|
|
* that will return non-zero when long filenames API should be used, zero
