What is the canonical way to check for errors using the CUDA runtime API?
...ccasionally we may wish to report and recover from an error condition in a C++ context as part of a larger application.
Here's a reasonably terse way to do that by throwing a C++ exception derived from std::runtime_error using thrust::system_error:
#include <thrust/system_error.h>
#include &...
How do you disable the unused variable warnings coming out of gcc in 3rd party code I do not wish to
...u need to use this function as a handler - which (imho) is quite common in C++ Boost library. Then you need the second formal parameter version, so the function's signature is the same as the template the handler requires, otherwise the compilation would fail. But you don't really need it in the fun...
What is managed or unmanaged code in programming?
...y language programs that have been assembled into machine
language and C/C++ programs compiled into machine language for a
particular platform are examples of unmanaged code.(Read more)
Native code is often synonymous with Unmanaged, but is not identical.
...
constant pointer vs pointer on a constant value [duplicate]
...ant and immutable but the pointed data is not.
You could use const_cast(in C++) or c-style cast to cast away the constness in this case as data itself is not constant.
const char * a;
means that the pointed data cannot be written to using the pointer a.
Using a const_cast(C++) or c-style cast to...
How do I print a double value with full precision using cout?

@MikeFisher You're right, C++11 introduces max_digits10 to denote the same. Fixed the answer to reflect this.

How do I create my own URL protocol? (e.g. so://…) [closed]
...use to do it reliably you can't do it in managed code and have to do it in C++ (I suppose you could use VB6). You should consider whether you really need to do this and if you do, design it carefully and code it securely. An attacker can easily control the content that gets passed to you by simply i...
How to determine if a string is a number with C++?
...eturn !s.empty() && it == s.end();
}
Or if you want to do it the C++11 way:
bool is_number(const std::string& s)
{
return !s.empty() && std::find_if(s.begin(),
s.end(), [](unsigned char c) { return !std::isdigit(c); }) == s.end();
}
