NAME

acl_set_fd − Sets the ACL on the file or directory designated by the file descriptor

SYNOPSIS

#include <sys/acl.h>
int acl_set_fd(
        int fd,
        acl_type_t type_d,
        acl_t acl_d );

LIBRARY

Security Library (libpacl.a)

PARAMETERS

fdRefers to the open file descriptor of the file or directory to set the ACL on. 

type_d
Designates the type of ACL to set: ACL_TYPE_ACCESS, ACL_TYPE_DEFAULT, or ACL_TYPE_DEFAULT_DIR.

acl_d
Working storage internal representation of the ACL that is being set.

DESCRIPTION

NOTE:  This function is based on Draft 13 of the POSIX P1003.6 standard. 

Given a file descriptor to a file or directory, the acl_set_fd() function sets the designated ACL. The type of ACL being set is determined by the type_d parameter. If acl_d is NULL then the designated ACL is removed from the designated file or directory. The entry pointer used by the acl_get_entry() function becomes undefined after a call to the acl_set_fd() function. 

RETURN VALUES

Upon successful completion, the acl_set_fd() function returns a value of 0 (zero).  Otherwise, a value of -1 is returned and errno is set to indicate the error. 

ERRORS

If any of the following conditions occur, the acl_set_fd() function sets errno to the corresponding value:

[EACCES]
The required access to the file was denied.

[EBADF]
The fd argument is not a valid file descriptor. 

[EINVAL]
The acl_d argument does not contain a valid ACL. Argument type_d does not contain a valid ACL type number. 

[ENOSPC]
The directory or file system that would contain the new ACL cannot be extended or the file system is out of file allocation resources.

[ENOTDIR]
The argument type_d indicates a default ACL, and fd does not point to a directory. 

[ENOTSUP]
The designated file or directory resides on a file system that does not support ACLs.

[EPERM]
The process does not have the appropriate permissions to perform the operation. The setting and changing of ACLs have been disabled by the system administrator.

[EPERM]
The designated file or directory resides on a read-only file system.
