Win32: simplify loading of DLL functions
Dynamic loading of DLL functions is duplicated in several places in Git
for Windows' source code.
This patch adds a pair of macros to simplify the process: the
DECLARE_PROC_ADDR(<dll>, <return-type>, <function-name>,
...<function-parameter-types>...) macro to be used at the beginning of a
code block, and the INIT_PROC_ADDR(<function-name>) macro to call before
using the declared function. The return value of the INIT_PROC_ADDR()
call has to be checked; If it is NULL, the function was not found in the
specified DLL.
Example:
DECLARE_PROC_ADDR(kernel32.dll, BOOL, CreateHardLinkW,
LPCWSTR, LPCWSTR, LPSECURITY_ATTRIBUTES);
if (!INIT_PROC_ADDR(CreateHardLinkW))
return error("Could not find CreateHardLinkW() function";
if (!CreateHardLinkW(source, target, NULL))
return error("could not create hardlink from %S to %S",
source, target);
return 0;
