NAME

       sysfs - get file system type information

SYNOPSIS

       #include <sys/fstyp.h>
       #include <sys/fsid.h>

       int sysfs(int opcode, const char *fsname);

       int sysfs(int opcode, int fs_index, char *buf);

       int sysfs(int opcode);

DESCRIPTION

       The  sysfs()  function  returns	information  about  the  file system types configured  in the system.  The number of arguments accepted by
       sysfs() depends on the opcode argument, which can take the following values:

       GETFSIND     Translate fsname, a null-terminated file-system type identifier, into a file-system type index.

       GETFSTYP     Translate fs_index, a file-system type index, into a null-terminated file-system type identifier and write it into the  buffer
		    pointed to by buf, which must be at least of size FSTYPSZ as defined in <sys/fstyp.h>.

       GETNFSTYP    Return the total number of file system types configured in the system.

RETURN VALUES

       Upon successful completion, the value returned depends upon the opcode argument as follows:

       GETFSIND     the file-system type index

       GETFSTYP     0

       GETNFSTYP    the number of file system types configured

       Otherwise, -1 is returned  and errno is set to indicate the error.

ERRORS

       The sysfs() function will fail if:

       EFAULT	 The buf or fsname argument points to an illegal address.

       EINVAL	 The fsname argument points to an invalid file-system identifier; the fs_index argument is 0 or invalid; or the opcode argument is
		 invalid.
