Line 349:
C99 introduced a few standard pragmas, taking the form <code>#pragma STDC ...</code>, which are used to control the floating-point implementation. The alternative, macro-like form {{code|_Pragma(...)}} was also added.
One of the most popular uses of the <code>#pragma</code> directive is [[pragma once|{{mono|#pragma once}}]], which behaves the same way an [[include guard|{{mono|#include}} guard]] would, condensed into a single directive placed at the top of the file. Despite the fact that it is non-standard, it is supported by most compilers.
