acl_delete_perm -- delete permissions from a permission set
Standard C Library (libc, -lc)
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; otherwise
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.

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.
