34 // These OS-Compatible (not C++) externs are included by XrdPosix.hh to
35 // complete the macro definitions contained therein.
36 
37 // Use this file directly to define your own macros or interfaces. Note that
38 // native types are used to avoid 32/64 bit parameter/return value ambiguities
39 // and to enforce shared library compatibility (needed by the preload32 code).
40 
41 // Only 64-bit interfaces are directly supported. However, the preload library
42 // supports the old 32-bit interfaces. To use this include you must specify
43 
44 // -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
45 
46 // compilation options. This ensures LP64 compatibility which defines:

49 // size_t -> unsigned long long
50 // off_t -> long long

57 
58 // We pre-declare various structure t avoid compilation complaints. We cannot
59 // include the necessary ".h" files as these would also try to define entry
60 // points which may conflict with our definitions due to renaming pragmas and
61 // simple defines. All we want is to make sure we have the right name in the
62 // loader's symbol table so that the preload library can intercept the call.
63 // We need these definitions here because the includer may not have included
64 // all of the includes necessary to support all of the API's.
