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 permission 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.
