NAME sysfs - get file system type information
, const char *
, unsigned int
, char *
() returns information about the file system types currently present in the kernel. The specific form of the
() call and the information returned depends on the
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.
RETURN VALUE 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.
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.
CONFORMING TO SVr4.
NOTES This System-V derived system call is obsolete; don't use it.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.
BUGS There is no libc or glibc support. There is no way to guess how large
buf should be.
