FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

acl_delete_perm - delete permissions from a permission set



      acl_delete_perm - delete permissions from a permission set


      Standard C Library (libc, -lc)


      #include <sys/types.h>
      #include <sys/acl.h>
      acl_delete_perm(acl_permset_t permset_d, acl_perm_t perm);


      The acl_delete_perm() function is a POSIX.1e call that removes specific
      permissions from permissions set perm.
      The acl_delete_perm() function returns the value 0 if successful; other‐
      wise the value -1 is returned and the global variable errno is set to
      indicate the error.


      The acl_delete_perm() function fails if:
      [EINVAL]           Argument permset_d is not a valid descriptor for a
                         permission set.  Argument perm does not contain a
                         valid acl_perm_t value.
      acl(3), acl_add_perm(3), acl_clear_perms(3), acl_get_permset(3),
      acl_set_permset(3), posix1e(3)


      POSIX.1e is described in IEEE POSIX.1e draft 17.


      POSIX.1e support was introduced in FreeBSD 4.0.  The acl_delete_perm()
      function was added in FreeBSD 5.0.


      The acl_delete_perm() function was written by Chris D. Faulhaber


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
