Differences and relationship between glActiveTexture and glBindTexture
...rent objects, and all of our object manipulation functions are adjusted to select from the current object.
When you change the currently active object, you change the entire set of target locations. So you can bind something that goes into current object 0, switch to current object 4, and will be m...
Realistic usage of the C99 'restrict' keyword?
...ons could be saved, as mentioned by supercat.
Consider for example:
void f(char *restrict p1, char *restrict p2) {
for (int i = 0; i < 50; i++) {
p1[i] = 4;
p2[i] = 9;
}
}
Because of restrict, a smart compiler (or human), could optimize that to:
memset(p1, 4, 50);
memset(...

Oh, and be careful if you're splitting on certain characters like a pipe |. You will need to escape the char stackoverflow.com/questions/3842537/…

Why is C so fast, and why aren't other languages as fast or faster? [closed]
...what the machine does can be seen in the rules that govern the widening of char objects for use in expressions: whether the values of char objects widen to signed or unsigned quantities typically depends on which byte operation is more efficient on the target machine.

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-...
Find out HTTP method in PHP [duplicate]
...g
filter_input( \INPUT_SERVER, 'REQUEST_METHOD', \FILTER_SANITIZE_SPECIAL_CHARS )
(you might of course use other filter, eg. FILTER_SANITIZE_STRING - see here for a full list).
