acl_add_perm -- add permissions to a permission set
Standard C Library (libc, -lc)
#include <sys/types.h>
#include <sys/acl.h>
int
acl_add_perm(acl_permset_t permset_d, acl_perm_t perm);
The acl_add_perm() function is a POSIX.1e call that adds the permission
contained in perm to the permission set permset_d.
Note: it is not considered an error to attempt to add permissions that
already exist in the permission set.
The acl_add_perm() function returns the value 0 if successful; otherwise
the value -1 is returned and the global variable errno is set to indicate
the error.
The acl_add_perm() function fails if:
[EINVAL] Argument permset_d is not a valid descriptor for a
permission set within an ACL entry. Argument perm
does not contain a valid acl_perm_t value.

POSIX.1e is described in IEEE POSIX.1e draft 17.
POSIX.1e support was introduced in FreeBSD 4.0. The acl_add_perm() function
was added in FreeBSD 5.0.
The acl_add_perm() function was written by Chris D. Faulhaber
