Method Detail

sysinfo

int sysinfo(LibC.Sysinfo info)

sysinfo() provides a simple way of getting overall system statistics. This is more portable than reading /dev/kmem.

Parameters:

info - A Sysinfo structure which will be populated

Returns:

On success, zero is returned. On error, -1 is returned, and errno is set appropriately.

statvfs

int statvfs(String path,
            LibC.Statvfs buf)

The function statvfs() returns information about a mounted filesystem.

Parameters:

path - the pathname of any file within the mounted filesystem.

buf - a pointer to a statvfs structure

Returns:

On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
