Get the device and inode number
#include <sys/resmgr.h>
int resmgr_devino( int id,
dev_t *pdevno,
ino64_t *pino );
- id
- The link ID that
resmgr_attach()
returned.
- pdevno
- A pointer to a dev_t object where the function can store
the device number.
- pino
- A pointer to a ino64_t object where the function can store
the inode number.
libc
Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The function resmgr_devino() fills in the
structures pointed to by pdevno and pino
with the device number and inode number extracted from id.
This function is typically used to fill in:
- iofunc_mount_t->dev
- iofunc_attr_t->inode
You can use the
major(), minor(), and makedev()
macros to work with device IDs. They're defined in
<sys/types.h> and are described in the documentation for
stat().
-1 on error
(errno is set); any other
value on success.
- EINVAL
- The id argument is invalid.
