setacl(2) setacl(2)

[ENOSYS] The function is not supported by this ﬁle system type.

[ENOSPC] Not enough space on the ﬁle system.

[ENFILE] System ﬁle table is full.

[EDQUOT] User’s disk quota block or inode limit has been reached for this ﬁle system.

EXAMPLES

The following code fragment deﬁnes and sets an ACL on ﬁle

../shared which allows the ﬁle’s owner to

read, write, and execute or search the ﬁle, and allows user 103, group 204 to read the ﬁle.

#include <unistd.h>

#include <sys/stat.h>

#include <sys/acl.h>

char *filename = "../shared";

struct acl_entry acl [2];

struct stat statbuf;

if (stat (filename, & statbuf) < 0)

error (...);

acl [0] . uid = statbuf . st_uid; /* file owner */

acl [0] . gid = ACL_NSGROUP;

acl [0] . mode = R_OK | W_OK | X_OK;

acl [1] . uid = 103;

acl [1] . gid = 204;

acl [1] . mode = R_OK;

if (setacl (filename, 2, acl))

error (...);

The following call deletes all optional ACL entries from file1:

setacl ("file1", ACL_DELOPT, (struct acl_entry *) 0);
