88 * Defining _WIN32_WINNT here in e_os.h implies certain "discipline."
89 * Most notably we ought to check for availability of each specific
90 * routine that was introduced after denoted _WIN32_WINNT with
91 * GetProcAddress(). Normally newer functions are masked with higher
92 * _WIN32_WINNT in SDK headers. So that if you wish to use them in
93 * some module, you'd need to override _WIN32_WINNT definition in
94 * the target module in order to "reach for" prototypes, but replace
95 * calls to new functions with indirect calls. Alternatively it
96 * might be possible to achieve the goal by /DELAYLOAD-ing .DLLs
97 * and check for current OS version instead.

101 # if defined(_WIN32_WINNT) || defined(_WIN32_WCE)
103 * Just like defining _WIN32_WINNT including winsock2.h implies
104 * certain "discipline" for maintaining [broad] binary compatibility.
105 * As long as structures are invariant among Winsock versions,
106 * it's sufficient to check for specific Winsock2 API availability
107 * at run-time [DSO_global_lookup is recommended]...

211 /* We don't have any well-defined random devices on VMS, yet... */
214 We need to do this since VMS has the following coding on status codes:
216 Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
217 The important thing to know is that odd numbers are considered
218 good, while even ones are considered errors.
219 Bits 3-15: actual status number
220 Bits 16-27: facility number. 0 is considered "unknown"
221 Bits 28-31: control bits. If bit 28 is set, the shell won't try to
222 output the message (which, for random codes, just looks ugly)
224 So, what we do here is to change 0 to 1 to get the default success status,
225 and everything else is shifted up to fit into the status number field, and
226 the status is tagged as an error, which is what is wanted here.
228 Finally, we add the VMS C facility code 0x35a000, because there are some
229 programs, such as Perl, that will reinterpret the code back to something
230 POSIX. 'man perlvms' explains it further.
232 NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
233 codes (status type = 1). I couldn't disagree more. Fortunately, the
234 status type doesn't seem to bother Perl.
