** Macros for test source code readability/maintainability.
**
** All of the following macros require that an int data type 'res' variable
** exists in scope where macro is used, and that it has been initialized to
** zero before the macro is used.
**
** exe_* and chk_* macros are helper macros not intended to be used from
** outside of this header file. Arguments 'Y' and 'Z' of these represent
** source code file and line number, while Arguments 'A', 'B', etc, are
** 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 tha 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
** as test result.
