iofunc_acl_default()
QNX SDP8.0C Library ReferenceAPIDeveloper
Default handler for the acl callout
Synopsis:
#include <sys/iofunc.h>
int iofunc_acl_default(
resmgr_context_t *ctp,
io_acl_t *msg,
iofunc_ocb_t *ocb );
Arguments:
- ctp
- A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
- msg
- A pointer to a io_acl_t structure that contains the message that the resource manager received; see the entry for iofunc_acl().
- ocb
- A pointer to the iofunc_ocb_t structure for the Open Control Block that was created when the client opened the resource.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The iofunc_acl_default() function provides default handling of _IO_ACL (access control lists) messages.
You can place this function directly into the resmgr_io_funcs_t table passed as the io_funcs argument to resmgr_attach(), at the acl position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
The iofunc_acl_default() function calls iofunc_acl_track() and iofunc_acl() to do the actual work.
Note:
ACLs will be supported for a device if either the attr->mount pointer is NULL,
or if the IOFUNC_PC_ACL bit is set in the conf member of the
iofunc_mount_t pointed to by a non-NULL attr->mount pointer.
For more information about ACLs, see Working with Access Control Lists (ACLs) in the QNX OS Programmer's Guide.
Returns:
