sysfs — get file system type information
int
sysfs( |
int option, |
const char *fsname); |

sysfs( |
int option, |

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:
Translate the file-system identifier string
fsname into a
file-system type index.
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 string.
Return the total number of file system types currently present in the kernel.
The numbering of the file-system type indexes begins with zero.
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.
Either fsname or buf is outside your
accessible address space.
fsname is
not a valid file-system 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This System-V derived system call is obsolete; don't use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.
