# NAME

`acl_set_tag_type` —
set the tag type of an ACL entry

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

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

int
`acl_set_tag_type`(acl_entry_t entry_d, acl_tag_t tag_type);

# DESCRIPTION

The `acl_set_tag_type`() function is a POSIX.1e call that sets the ACL tag type of ACL entry entry_d to the value of tag_type.

Valid values are:

ACL_USER_OBJ | Permissions apply to file owner
ACL_USER | Permissions apply to additional user specified by qualifier
ACL_GROUP_OBJ | Permissions apply to file group
ACL_GROUP | Permissions apply to additional group specified by qualifier
ACL_MASK | Permissions specify mask
ACL_OTHER | Permissions apply to other
ACL_OTHER_OBJ | Same as ACL_OTHER
ACL_EVERYONE | Permissions apply to everyone@

Calling `acl_set_tag_type`() with tag_type equal to ACL_MASK, ACL_OTHER or ACL_OTHER_OBJ brands the ACL as POSIX.1e. Calling it with ACL_EVERYONE brands the ACL as NFSv4.

# RETURN VALUES

The `acl_set_tag_type`() 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_set_tag_type`() function fails if:

[`EINVAL`]
  Argument entry_d is not a valid descriptor for an ACL entry. Argument tag_type is not a valid ACL tag type. ACL is already branded differently.
