They are typically used by monitoring and administration programs to perform specific functions not supported by the high-level CUPS API functions.</p> <h2 class='title'>General Usage</h2> <p>The <var><cups/cups.h></var> header file must be included to use the HTTP and IPP functions.</p> <p>Programs using these functions must be linked to the CUPS library: <var>libcups.a</var>, <var>libcups.so.2</var>, <var>libcups.2.dylib</var>, <var>libcups_s.a</var>, or <var>libcups2.lib</var> depending on the platform. The following command compiles <var>myprogram.c</var> using GCC and the CUPS library:</p> <pre class='command'> <kbd>gcc -o myprogram myprogram.c -lcups</kbd> </pre> <h2 class='title'>Compatibility</h2> <p>Unless otherwise specified, the HTTP and IPP API functions require CUPS 1.1 or higher.</p>
