`acl_add_flag_np` —
add flags to a flagset

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

`#include <sys/types.h>`

int
`acl_add_flag_np`(acl_flagset_t flagset_d, acl_flag_t flag);

# DESCRIPTION

The `acl_add_flag_np`() function is a non-portable call that adds the NFSv4 ACL flags contained in flags to the flagset flagset_d.

Note: it is not considered an error to attempt to add flags that already exist in the flagset.

Valid values are:

ACL_ENTRY_FILE_INHERIT | Will be inherited by files.
ACL_ENTRY_DIRECTORY_INHERIT | Will be inherited by directories.
ACL_ENTRY_NO_PROPAGATE_INHERIT | Will not propagate.
ACL_ENTRY_INHERIT_ONLY | Inherit-only.
ACL_ENTRY_INHERITED | Inherited from parent

# RETURN VALUES

The `acl_add_flag_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_add_flag_np`() function fails if:

[`EINVAL`]
  Argument flagset_d is not a valid descriptor for a flagset within an ACL entry. Argument flag does not contain a valid acl_flag_t value.
