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. For POSIX.1e ACLs, valid values are: ACL_EXECUTE Execute permission ACL_WRITE Write permission ACL_READ Read permission For NFSv4 ACLs, valid values are: ACL_READ_DATA Read permission ACL_LIST_DIRECTORY Same as ACL_READ_DATA ACL_WRITE_DATA Write permission, or permission to create files ACL_ADD_FILE Same as ACL_READ_DATA ACL_APPEND_DATA Permission to create directories. Ignored for files ACL_ADD_SUBDIRECTORY Same as ACL_APPEND_DATA ACL_READ_NAMED_ATTRS Ignored ACL_WRITE_NAMED_ATTRS Ignored ACL_EXECUTE Execute permission ACL_DELETE_CHILD Permission to delete files and subdirectories ACL_READ_ATTRIBUTES Permission to read basic attributes ACL_WRITE_ATTRIBUTES Permission to change basic attributes ACL_DELETE Permission to delete the object this ACL is placed on ACL_READ_ACL Permission to read ACL ACL_WRITE_ACL Permission to change the ACL and file mode ACL_SYNCHRONIZE Ignored Calling acl_add_perm() with perm equal to ACL_WRITE or ACL_READ brands the ACL as POSIX. Calling it with ACL_READ_DATA, ACL_LIST_DIRECTORY, ACL_WRITE_DATA, ACL_ADD_FILE, ACL_APPEND_DATA, ACL_ADD_SUBDIRECTORY, ACL_READ_NAMED_ATTRS, ACL_WRITE_NAMED_ATTRS, ACL_DELETE_CHILD, ACL_READ_ATTRIBUTES, ACL_WRITE_ATTRIBUTES, ACL_DELETE, ACL_READ_ACL, ACL_WRITE_ACL or ACL_SYNCHRONIZE brands the ACL as NFSv4. 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. ACL is already branded differently. SEE ALSO

ACL_PERMSET_MASK(3)					   BSD Library Functions Manual 				       ACL_PERMSET_MASK(3)

NAME
acl_permset_mask -- Manipulate ACL permissions using bitmasks LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/types.h> #include <sys/acl.h> int acl_maximal_permset_mask_np(acl_permset_mask_t * mask_p); int acl_get_permset_mask_np(acl_entry_t entry_d, acl_permset_mask_t * mask_p); int acl_set_permset_mask_np(acl_entry_t entry_d, acl_permset_mask_t mask); DESCRIPTION
The acl_permset_mask_t functions are a Darwin extension to the POSIX.1e ACL standard which allow manipulation of permissions in an acl_entry_t using a bitmask of type acl_permset_mask_t rather than a constructed acl_permset_t (as done by acl_get_permset(3) and acl_set_permset(3)). acl_permset_mask_t values may be constructed using bitwise operations over acl_perm_t values. acl_maximal_permset_mask_np() sets the value pointed to by mask_p to a bitmask of all valid acl_perm_t values. acl_get_permset_mask_np() returns via mask_p a bitmask of permissions set on the ACL entry entry_d. acl_set_permset_mask_np() sets the permissions of ACL entry entry_d to match the permission bitmask provided by mask. RETURN VALUES
The acl_maximal_permset_mask_np() 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_get_permset_mask_np() 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_set_permset_mask_np() 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_get_permset_mask_np() function fails if: [EINVAL] Argument entry_d is not a valid descriptor for an ACL entry. The acl_set_permset_mask_np() function fails if: [EINVAL] Argument entry_d is not a valid descriptor for an ACL entry. [EINVAL] Argument mask is not a valid bitmask of ACL permissions. SEE ALSO
