SYNOPSIS
#include <sys/acl.h>
int acl_set_file(
char *path_p,
acl_type_t type_d,
acl_t acl_d );
LIBRARY
Security Library (libpacl.a)
PARAMETERS
The pathname 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.
DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 stan‐
dard.
Given a path name to a file or directory, the acl_set_file() 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_file() function.
RETURN VALUES
Upon successful completion, the acl_set_file() 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_file() function
sets errno to the corresponding value:
The required access to the file was denied. The named file or direc‐
tory does not exist. The argument acl_d does not contain a valid ACL.
Argument type_d does not contain a valid ACL type. The pathname is
longer than allowed. The directory or file system that would contain
the new ACL cannot be extended or the file system is out of file allo‐
cation resources. The argument type_d indicates a default ACL, and
path_p does not point to a directory. The designated file or directory
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 adminis‐
trator. The designated file or directory resides on a read-only file
system.
