What does static_assert do, and what would you use it for?
...ou can put a static assert like this
static_assert(sizeof(unsigned int) * CHAR_BIT == 32);
in your code. On another platform, with differently sized unsigned int type the compilation will fail, thus drawing attention of the developer to the problematic portion of the code and advising them to re-...
What is the difference between sigaction and signal?
...s defined in the C standard. Nevertheless, it has a number of undesirable characteristics that sigaction() avoids - unless you use the flags explicitly added to sigaction() to allow it to faithfully simulate the old signal() behaviour.
The signal() function does not (necessarily) block other signa...
What is the canonical way to check for errors using the CUDA runtime API?
...ans), __FILE__, __LINE__); }
inline void gpuAssert(cudaError_t code, const char *file, int line, bool abort=true)
{
if (code != cudaSuccess)
{
fprintf(stderr,"GPUassert: %s %s %d\n", cudaGetErrorString(code), file, line);

You can then wrap each API ...
What are the rules for the “…” token in the context of variadic templates?
...ttern = z<T>(args)
}
Now if I call this function passing T as {int, char, short}, then each of the function call is expanded as:
g( arg0, arg1, arg2 );
h( x(arg0), x(arg1), x(arg2) );
m( y(arg0, arg1, arg2) );
n( z<int>(arg0), z<char>(arg1), z<short>(arg2) );

else
puts("stdin is NOT connected to a terminal");
return 0;
