Introduction

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.

General Usage

The <cups/cups.h> header file must be included to use the HTTP and IPP functions.

Programs using these functions must be linked to the CUPS library: libcups.a, libcups.so.2, libcups.2.dylib, libcups_s.a, or libcups2.lib depending on the platform. The following command compiles myprogram.c using GCC and the CUPS library:

gcc -o myprogram myprogram.c -lcups

Compatibility

Unless otherwise specified, the HTTP and IPP API functions require CUPS 1.1 or higher.
