51<H2>Description</H2>
52<p>
53Opens a file. Proper access rights are required to open a file. You can't open files if you don't have permission to access those files.

57This function sometimes puts the current thread to sleep, so it cannot be called from callback functions. For precautions related to calling similar functions, see <a href="../os/Interrupt/intro.html">Interrupts and Callback Functions</a>.
