acl_delete_perm — delete a permission from an ACL permission set
Linux Access Control Lists library (libacl, -lacl).
#include <sys/types.h> #include <sys/acl.h> int acl_delete_perm(acl_permset_t permset_d, acl_perm_t perm);
The acl_delete_perm() function deletes the permission contained in the argument perm (one of ACL_READ, ACL_WRITE, ACL_EXECUTE) from the permission set referred to by the argument permset_d. An attempt to delete a permission that is not contained in the permission set is not considered an error. Any existing descriptors that refer to permset_d continue to refer to that permission set.
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.
If any of the following conditions occur, the acl_delete_perm() function returns -1 and sets errno to the corresponding value: [EINVAL] The argument permset_d is not a valid descriptor for a permission set within an ACL entry. The argument perm does not contain a valid acl_perm_t value.
