CentOS 7.0 - man page for sysfs (centos section 2)

SYSFS(2)			    Linux Programmer's Manual				 SYSFS(2)

NAME
       sysfs - get file system type information

SYNOPSIS
       int sysfs(int option, const char *fsname);

       int sysfs(int option, unsigned int fs_index, char *buf);

       int sysfs(int option);

DESCRIPTION
       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 iden-
	  tifier string.  This string will be written to the buffer pointed to by buf.	Make sure
	  that buf has enough space to accept the string.

       3  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.

ERRORS
       EFAULT Either fsname or buf is outside your accessible address space.

       EINVAL 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       This System-V derived system call is obsolete; don't use it.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.
