msvcrt

问题 For comparing any strings without considering their case, there are various C library functions such as strcasecmp() , stricmp() and stricmpi() . What is the difference between these? 回答1: There are multiple ways to do many things primarily because the standards process lags behind implementations. People see the need for a function (in this case, case insensitive string comparison) and some compiler writers/library writers implement a function called strcmpi , while another group implements

问题 So here's a fun one... we have a few C libraries which should be platform independent, even though they were developed on linux, because they only rely on the c standard library as defined in ISO/IEC 9899:1999. When we compiled those libraries with MinGW everything seemed to work fine at first, but today we found out that the snprintf() implementation of msvcrt is braindea... sorry, i meant " incompatible " with the definition in the C99 standard. I would have expected a warning from MinGW,

问题 I'm writing a language using LLVM. I'd like to avoid having to package clang and simply use the LLVM tools (ex. lld, lld-link). I've been trying to invoke the printf function from my simple IR code ( testinput.ll ): ; ModuleID = 'Test2' source_filename = "entry" @str_0 = private unnamed_addr constant [13 x i8] c"Hello world!\00" declare i32 @printf(i8*, ...) define i32 @main() { entry: %anonymous_10 = call i32 (i8*, ...) @printf(i8* getelementptr inbounds ([13 x i8], [13 x i8]* @str_0, i32 0,

问题 From what I read about these posting and elsewhere, regarding the issue of why I cannot install Microsoft VC++ 2015 runtime redistributable if I already have Microsoft VC++ 2017 runtime installed. The reason for this "cannot install" is because once you have Microsoft VC++ 2017 installed, there is no need to install 2015 version,as 2017 subsume 2015. Am I right? Secondly, and more crucially, from now onwards if I have a higher version of Microsoft VC++ installed, I can safely skip the lower

问题 I have the following code from one class: class _Getch: def __init__(self): self.impl = _GetchWindows() def read_key(self): return self.impl() class _GetchWindows: def __init__(self): import msvcrt def __call__(self): import msvcrt return msvcrt.getch() And then I have another class that imported _Getch. Within this other class, I tried to use the read_key provided by _Getch to do things in the conditional: r = _Getch() key = r.read_key() print(key) if key = 'a': #do things elif key = 's': #

问题 I have an assembly with the following manifest embedded: <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC80.CRT" version="8.0.50608.0" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity> </dependentAssembly> </dependency> </assembly> On one of my machines this assembly doesn't work (the assembly fails to load). Opening this in dependency walker gives me the

问题 Edit: unlike the case in the question noted in the vote-to-close, the offending code here is CRT code, not mine . Even if it has a problem (which I'm pretty sure it doesn't), I have no way of fixing its source. We have some legacy memory-leak tracing code that uses some CRT internals (nothing too exotic, essentially _CrtMemBlockHeader which is sort-of documented). While trying to migrate from VS2010 to VS2013 the code seems to cause sporadic build failures, and the offending part can be

问题 void start() { stuff(); //code before mainCRTStartup mainCRTStartup(); } int main() { //other code } In Visual C++,it compiles fine and function "stuff()" gets called before main. How would call "stuff()" before "mainCRTStartup()"? on Mingw(OS:Windows NT)? it seems to ignore "void start()". 回答1: You could use the -e argument to ld (the linker) to specify start as your entry point. I'm not sure how to feed arguments to ld using mingw; perhaps someone can edit my answer to provide that. 回答2:
