- Disable warning C4127 "conditional expression is constant" globally
in curl_setup.h for when building with Microsoft's compiler.
This mainly affects building with the Visual Studio project files found
in the projects dir.
Prior to this change the cmake and winbuild build systems already
disabled 4127 globally for when building with Microsoft's compiler.
Also, 4127 was already disabled for all build systems in the limited
circumstance of the WHILE_FALSE macro which disabled the warning
specifically for while(0). This commit removes the WHILE_FALSE macro and
all other cruft in favor of disabling globally in curl_setup.
Background:
We have various macros that cause 0 or 1 to be evaluated, which would
cause warning C4127 in Visual Studio. For example this causes it:
#define Curl_resolver_asynch() 1
Full behavior is not clearly defined and inconsistent across versions.
However it is documented that since VS 2015 Update 3 Microsoft has
addressed this somewhat but not entirely, not warning on while(true) for
example.
Prior to this change some C4127 warnings occurred when I built with
Visual Studio using the generated projects in the projects dir.

** zero before the macro is used.
|
|

|

|
|
** the arguments used to actually call a libcurl function.

** All easy_* and multi_* macros call a libcurl function and evaluate if
|
|
** the function has succeeded or failed. When the function succeeds 'res'
|
|
** variable is not set nor cleared and program continues normal flow. On
|
|
** the other hand if function fails 'res' variable is set and a jump to
|
|
** label 'test_cleanup' is performed.
|

**
|
|
** Every easy_* and multi_* macros have a res_easy_* and res_multi_* macro
|
|
** counterpart that operates in the same way with the exception that no
|
|
** jump takes place in case of failure. res_easy_* and res_multi_* macros
|
|
** should be immediately followed by checking if 'res' variable has been
|
|
** set.
|
|
**
|
|
** 'res' variable when set will hold a CURLcode, CURLMcode, or any of the
|
|
** TEST_ERR_* values defined above. It is advisable to return this value
