Linux Man Pages

295

The Linux man-pages project documents the Linux kernel and C library interfaces that are employed by user programs. It provides manual pages in the following sections:

  • 2: System calls, documenting the system calls provided by the Linux kernel.
  • 3: Library functions, documenting the functions provided by the standard C library (with particular focus on glibc, the GNU C library).
  • 4: Devices, which documents details of various devices, most of which reside in /dev.
  • 5: Files, which describes various file formats, and includes proc(5), which documents the /proc file system.
  • 7: Overviews, conventions, and miscellaneous.
