LAM_RFSTATE(2) LAM REMOTE LIBRARY LAM_RFSTATE(2)NAME
lam_rfstate - Report status of remote LAM file descriptors.
SYNOPSIS
#include <freq.h>
int lam_rfstate(int node, struct fstate *table, int maxsize);
DESCRIPTION
The remote function lam_rfstate() accesses a remote LAM file daemon and
returns status information on all file descriptors.
The arguments to lam_rfstate() are: node, the target node identifier;
table, an array of structures where status information will be stored;
and maxsize, the number of elements in that array.
The file status structure is defined in <freq.h>.
struct fstate {
int fs_tfd
int fs_tflags
int fs_flow
int fs_src_node
int fs_src_event
int fs_ncubix
int fs_nheard
int fs_req
char fs_name[24]
};
fs_tfd LAM file handle
fs_tflags LAM, POSIX, and internal filed flags
fs_flow total amount of data transferred to date
fs_src_node last client's nodeid
fs_src_event last client's reply event (negative PID)
fs_name trailing 24 bytes of file name
The fs_tflags field contains the original POSIX and LAM open flags as
well as extra status flags added by the file daemon. See open(2) for
information on POSIX open flags. See lam_rfposix(2) for information on
LAM open flags. The LAM status flags are defined in <freq.h>.
FACTIVE The LAM file descriptor has an associated open POSIX file de‐
scriptor.
FLOCK The descriptor is permanently FACTIVE.
RETURN VALUE
Upon successful completion, the number of open file descriptors man‐
anged by the remote file daemon is returned. The return value may be
more or less than maxsize. If an error occurred, -1 is returned and
the global variable errno is set to indicate the type of error.
