acl_get_file — get an ACL by filename Linux Access Control Lists library (libacl, -lacl). #include < acl_t The In order to read an ACL from an object, a process must have read access to the object's attributes. The value of the argument type is used to indicate whether the access ACL or the default ACL associated with path_p is returned. If type is ACL_TYPE_ACCESS, the access ACL of path_p is returned. If type is ACL_TYPE_DEFAULT, the default ACL of path_p is returned. If type is ACL_TYPE_DEFAULT and no default ACL is associated with the directory path_p, then an ACL containing zero ACL entries is returned. If type specifies a type of ACL that cannot be associated with path_p, then the function fails. This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free(3) with the (void*)acl_t returned by On success, this function returns a pointer to the working storage. On error, a value of If any of the following conditions occur, the Search permission is denied for a component of the path prefix or the object exists and the process does not have appropriate access rights. Argument type specifies a type of ACL that cannot be associated with path_p. The argument type is not ACL_TYPE_ACCESS or ACL_TYPE_DEFAULT. The length of the argument path_p is too long. The named object does not exist or the argument path_p points to an empty string. The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints. A component of the path prefix is not a directory. The file system on which the file identified by path_p is located does not support ACLs, or ACLs are disabled.

acl_get_file
(const char *path_p, acl_type_t type); Description
acl_get_file
() function retrieves the access ACL associated with a file or directory, or the default ACL associated with a directory. The pathname for the file or directory is pointed to by the argument path_p. The ACL is placed into working storage and acl_get_file
() returns a pointer to that storage. acl_get_file
() as an argument. Return Value
(acl_t)NULL
is returned, and errno is set appropriately. Errors
acl_get_file
() function returns a value of (acl_t)NULL
and sets errno to the corresponding value: EACCES
