#include <sys/mount.h>
char *getvfsbynumber(
int typeno);
Specifies the number that identifies the type of the file system.
The getvfsbynumber() function returns the symbolic name for the virtual file system type identified by typeno. The type number of a mounted file system can be determined with the statfs() function.
The getvfsbynumber() function may not be able to handle file systems that are dynamically loaded.
Upon successful completion, getvfsbynumber() returns a symbolic name. Otherwise, getvfsbynumber() returns a value of -1 and sets errno.
If any of the following conditions occurs, the getvfsbynumber() function sets errno to the corresponding value: typeno is outside the range of known file system types.
Functions: statfs(2), getvfsbyname(3). delim off
