SYNOPSIS

#include <lkmi.h >

int lkmi_inodes (register lkmi_inodes_t *inodes_info)

PARAMETERS

inodes_info: Pointer to structure which is described below.

DESCRIPTION

Function retrieves kernel informations about used and allocated i-nodes using /proc/sys/fs/inode-nr and /proc/sys/fs/inode-max files. In older kernels are files placed /proc/sys/kernel/inode-nr and /proc/sys/kernel/inode-max. These files are tried if first file is not available. Fills structure lkmi_inodes_t which contains these fields.

max: Maximum number of i-node entries that can be allocated.
allocated: Current number of allocated i-node entries.
current: Current number of allocated i-node entries

RETURN VALUE

On success, zero is returned. If one of files is missing then partial value(s) is not retrieved. On error, -1 is returned, and errno is set appropriately.

If some value is missing the field is set to LKMI_NOTAVAILABLE.

EINVAL: Passed pointer to inodes_info is NULL.
other: See fopen(3) function, which causes other errors.
