| <h2 class='title'>Introduction</h2> |
| |
| <p>The CUPS HTTP and IPP APIs provide low-level access to the |
| HTTP and IPP protocols and CUPS scheduler. 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> |
