Get the access control list associated with a file descriptor
#include <sys/acl.h> acl_t acl_get_fd( int fd );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The acl_get_fd() function gets the ACL of the object associated with the given file descriptor, puts it into working storage, and returns a pointer to that storage. When you're finished with the ACL, you should call acl_free() to release it.
A pointer to the ACL in working storage, or NULL if an error occurred (errno is set).
This function is based on the withdrawn POSIX draft P1003.1e.
