I’m no expert, but cppreference.com has what appears to me to be some pretty good information on volatile. Here’s the gist of it: Every access (both read and write) made through an lvalue expression of volatile-qualified type is considered an observable side effect for the purpose of optimization and is evaluated strictly according to the … Read more
TortoiseGit (as of 2.14) requires a command-line git.exe. It works with a variety of different “git.exe providers”. Known to work are: Git for Windows 2.24+ (https://gitforwindows.org/, based on MSYS2; portable and installer are known to work; recommended; for Git for Windows >= 2.16 you need at least TortoiseGit 2.5.7; older versions of Git are not … Read more
OPA (Open Portable Atomics) could be a good fit for your needs. https://trac.mcs.anl.gov/projects/openpa/ It provides a consistent C API to common atomic operations across multiple platforms under an MIT-style license. The library is small and certainly meets your size requirements. The current platform list is: GCC inline assembly for x86, x86_64, ia64, PPC 440, and … Read more
int is a “most efficient type” in speed/size – but that is not specified by per the C spec. It must be 16 or more bits. int_fast16_t is most efficient type in speed with at least the range of a 16 bit int. Example: A given platform may have decided that int should be 32-bit … Read more
Update (Aug-2016): This question is no longer relevant, as msys2 now comes with cygpath in its installation. … I’ll summarize my research here. The cygpath equivalent in MSYS is to use this command: { cd /c/some/path && pwd -W; } | sed ‘s”https://stackoverflow.com/”\\|g’ The problem with this approach is that it requires existing path, e.g. … Read more
Try using ftp.nlst(dir). However, note that if the folder is empty, it might throw an error: files = [] try: files = ftp.nlst() except ftplib.error_perm as resp: if str(resp) == “550 No files found”: print “No files in this directory” else: raise for f in files: print f
That is ADL (Argument Dependent Lookup) or Koenig Lookup (for the designer of the feature). The purpose of the feature is that in many cases the same namespace will contain types and functions that can be applied to those types, all of which conform the interface. If ADL was not in place, you would have … Read more
1) Is there any additional function calling overhead when using someClass.operator+() No, if the function body is small and in the header, it will be inlined, and have no overhead 2) Is there a way to automatically make the compiler cast the floatWrapper to a float? struct floatWrapper { floatWrapper(float); //implicit conversion from float operator … Read more
In C++14, you can mark a function as deprecated using the [[deprecated]] attribute (see section 7.6.5 [dcl.attr.deprecated]). The attribute-token deprecated can be used to mark names and entities whose use is still allowed, but is discouraged for some reason. For example, the following function foo is deprecated: [[deprecated]] void foo(int); It is possible to provide … Read more
You could use the following test to differentiate Octave from MATLAB: isOctave = exist(‘OCTAVE_VERSION’, ‘builtin’) ~= 0;
