statfs64 *buf, int bufsize, int
function returns information about all mounted file systems. The
buf argument is a pointer to an array of
statfs structures (see
statfs(2) indicates, the structure is
defined differently depending on whether the macro
_DARWIN_FEATURE_64_BIT_INODE is defined (see
stat(2) for more information on this
Fields that are undefined for a particular file system are set to -1. The buffer is filled with an array of statfs structures, one for each mounted file system up to the size specified by bufsize.
If buf is given as NULL,
returns just the number of mounted file systems.
If flags is set to
will directly return the information retained in the kernel to avoid delays
caused by waiting for updated information from a file system that is perhaps
temporarily unable to respond. Some of the information returned may be out
of date, however; if flags is set to
getfsstat() will request updated
information from each mounted filesystem before returning.
Upon successful completion, the number of statfs structures is returned. Otherwise, -1 is returned and the global variable errno is set to indicate the error.
getfsstat() fails if one or more of the
following are true:
getfsstat64() routine is equivalent to

there is no longer any reason to use it (it will be removed in the
