Creates a path from a set of points [{x:?,y:?},{x:?,y:?},...,{x:?,y:?}] with rounded corners of radius. If the corner angle is too small to fit the radius or the distance between corners does not allow room the corners radius is reduced to a best fit. Usage Example var triangle = [ { x: 200...

C99 Since C99 the C library has a set of safe conversion functions that interpret a string as a number. Their names are of the form strtoX, where X is one of l, ul, d, etc to determine the target type of the conversion double strtod(char const* p, char** endptr); long double strtold(char const* p...

Official documentation: http://erlang.org/doc/tutorial/nif.html NIFs were introduced in Erlang/OTP R13B03 as an experimental feature. The purpose is to allow calling C-code from inside Erlang code. NIFs are implemented in C instead of Erlang, but they appear as any other functions in the scope of ...
