IOCTL-XFS...NITORED-FS(2) System Calls Manual IOCTL-XFS...NITORED-FS(2)
ioctl_xfs_health_fd_on_monitored_fs - check if the given fd
belongs to the same fs being monitored
#include <xfs/xfs_fs.h>
int ioctl(int healthmon_fd, XFS_IOC_HEALTH_FD_ON_MONITORED_FS,
struct xfs_health_file_on_monitored_fs *arg);
This XFS healthmon fd ioctl asks the kernel driver if the file
descriptor passed in via arg points to a file on the same
filesystem that is being monitored by healthmon_fd. The file
descriptor is conveyed in a structure of the following form:
struct xfs_health_file_on_monitored_fs {
__s32 fd;
__u32 flags;
};
The field flags must be zero.
The field fd is a descriptor of an open file.
The argument healthmon_fd must be a file opened via the
XFS_IOC_HEALTH_MONITOR ioctl.
On error, -1 is returned, and errno is set to indicate the error.
If the file descriptor points to a file on the same filesystem
that is being monitored, 0 is returned.
Error codes can be one of, but are not limited to, the following:
ESTALE The open file is not on the same filesystem that is being
monitored.
EINVAL One or more of the arguments specified is invalid.
EBADF arg.fd does not refer to an open file.
EFAULT The arg structure could not be copied into the kernel.
ENOTTY healthmon_fd is not a XFS health monitoring file.
This API is specific to XFS filesystem on the Linux kernel.
