sysfs — get filesystem type information
int
sysfs( |
int option, |
const char *fsname); |
int
sysfs( |
int option, |
| unsigned int fs_index, | |
char *buf); |
int
sysfs( |
int option); |
sysfs() returns information
about the filesystem types currently present in the kernel.
The specific form of the sysfs() call and the information returned
depends on the option
in effect:
Translate the filesystem identifier string
fsname into a
filesystem type index.
Translate the filesystem type index fs_index into a
null-terminated filesystem identifier string. This
string will be written to the buffer pointed to by
buf. Make sure
that buf has
enough space to accept the string.
Return the total number of filesystem types currently present in the kernel.
The numbering of the filesystem type indexes begins with zero.
On success, sysfs() returns
the filesystem index for option 1, zero for option 2, and the number of currently configured
filesystems for option 3. On
error, −1 is returned, and errno is set appropriately.
Either fsname or buf is outside your
accessible address space.
fsname is
not a valid filesystem type identifier; fs_index is
out-of-bounds; option is invalid.
This System-V derived system call is obsolete; don't use
it. On systems with /proc, the
same information can be obtained via /proc/filesystems; use that interface
instead.
