ACL_ADD_PERM(3)          BSD Library Functions Manual          ACL_ADD_PERM(3)

NAME
     acl_add_perm -- add permissions to a permission set

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_add_perm(acl_permset_t permset_d, acl_perm_t perm);

DESCRIPTION
     The acl_add_perm() function is a POSIX.1e call that adds the permission contained in perm to the per-mission permission
     mission set permset_d.

     Note: it is not considered an error to attempt to add permissions that already exist in the permission
     set.

RETURN VALUES
     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.

ERRORS
     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.

SEE ALSO
     acl(3), acl_clear_perms(3), acl_delete_perm(3), acl_get_permset(3), acl_set_permset(3), posix1e(3)
