acl_set_fd - Sets the ACL on the object designated by the file descriptor
Security Library (libpacl.a)
Refers to the open file descriptor of the file or directory to set the ACL on. Designates the type of ACL to set: ACL_TYPE_ACCESS, ACL_TYPE_DEFAULT, or ACL_TYPE_DEFAULT_DIR. Working storage internal representation of the ACL that is being set.
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard. The function may change as the P1003.6 standard is finalized.
Given a file descriptor to an object, the acl_set_fd() function sets the designated ACL. The type of ACL being set is determined by the acl_tag_t parameter. If acl_d is NULL then the designated ACL will be removed from the designated object. The entry pointer used by the acl_get_entry() function becomes undefined after a call to the acl_set_fd() function.
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.
If any of the following conditions occur, the acl_set_fd() function sets errno to the corresponding value:
The required access to the file was denied. The fd argument is not a valid file descriptor. The acl_d argument does not contain a valid ACL.
Argument type_d does not contain a valid ACL type number. The directory or file system that would contain the new ACL cannot be extended or the file system is out of file allocation resources. The argument type_d indicates a default ACL, and fd does not point to a directory object. The designated object resides on a file system that does not support ACLs 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. The designated object resides on a read-only file system.
