/**
|
|
* rationale: the Windows headers declare many POSIX functions (e.g. read).
|
|
* unfortunately, these are often slightly incorrect (size_t vs. size_t).
|
|
* to avert trouble in user code caused by these differences, we declare
|
|
* all functions ourselves according to SUSv3 and do not use the headers.
|
|
*
|
|
* however, it does not end there. some other libraries (e.g. wxWidgets)
|
|
* will want to pull in these headers, which would conflict with our
|
|
* declarations. also, our implementation uses the actual CRT code,
|
|
* so we want those functions (e.g. _read) to be declared correctly even
|
|
* if switching compiler/CRT version.
|
|
*
|
|
* how can these conflicting requirements be reconciled? our headers \#include
|
|
* "no_crt_posix.h" to \#define the CRT headers' include guards and thus
|
|
* prevent them from declaring anything. the implementation files \#include
|
|
* "crt_posix.h", which pulls in the CRT headers (even if "no_crt_posix.h"
|
|
* was previously included, e.g. in the PCH). note that the CRT headers
|
|
* would still cause conflicts with the POSIX function declarations,
|
|
* but we are able to prevent this via __STDC__.
