// These OS-Compatible (not C++) externs are included by XrdPosix.hh to
// complete the macro definitions contained therein.
// Use this file directly to define your own macros or interfaces. Note that
// native types are used to avoid 32/64 bit parameter/return value ambiguities
// and to enforce shared library compatibility (needed by the preload32 code).
// Only 64-bit interfaces are directly supported. However, the preload library
// supports the old 32-bit interfaces. To use this include you must specify
// -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
// compilation options. This ensures LP64 compatibility which defines:
//
// ssize_t -> long long
// size_t -> unsigned long long
// off_t -> long long
#if (!defined(_LARGEFILE_SOURCE) || !defined(_LARGEFILE64_SOURCE) || \
_FILE_OFFSET_BITS!=64) && !defined(XRDPOSIXPRELOAD32)
#error Compilation options are incompatible with XrdPosixExtern.hh; \
Specify -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
#endif
// We pre-declare various structure t avoid compilation complaints. We cannot
// include the necessary ".h" files as these would also try to define entry
// points which may conflict with our definitions due to renaming pragmas and
// simple defines. All we want is to make sure we have the right name in the
// loader's symbol table so that the preload library can intercept the call.
// We need these definitions here because the includer may not have included
// all of the includes necessary to support all of the API's.
