sysfs - get file system 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 file system types
currently present in the kernel. The specific form of the
sysfs call and the information returned depends on the
option in effect:
1 Translate the file-system identifier string fsname into
a file-system type index.
2 Translate the file-system type index fs_index into a
null-terminated file-system identifier string. This
string will be written to the buffer pointed to by buf.
Make sure that buf has enough space to accept the
3 Return the total number of file system types currently
present in the kernel.
The numbering of the file-system type indexes begins with
On success, sysfs returns the file-system index for option
1, zero for option 2, and the number of currently configured
file systems for option 3. On error, -1 is returned, and
errno is set appropriately.
fsname is not a valid file-system type identifier;
fs_index is out-of-bounds; option is invalid.
Either fsname or buf is outside your accessible address
