I didn't find the function statvfs(const char *path, struct statvfs *buf);

I want to use this function to know how much space is free on a drive partition

```c
NAME
statvfs, fstatvfs - get file system statistics

SYNOPSIS
#include

int statvfs(const char *path, struct statvfs *buf);
int fstatvfs(int fd, struct statvfs *buf);

DESCRIPTION
The function statvfs() returns information about a mounted file system.
path is the pathname of any file within the mounted file system. buf
is a pointer to a statvfs structure defined approximately as follows:

struct statvfs {
unsigned long f_bsize; /* file system block size */
unsigned long f_frsize; /* fragment size */
fsblkcnt_t f_blocks; /* size of fs in f_frsize units */
fsblkcnt_t f_bfree; /* # free blocks */
fsblkcnt_t f_bavail; /* # free blocks for unprivileged users */
fsfilcnt_t f_files; /* # inodes */
fsfilcnt_t f_ffree; /* # free inodes */
fsfilcnt_t f_favail; /* # free inodes for unprivileged users */
unsigned long f_fsid; /* file system ID */
unsigned long f_flag; /* mount flags */
unsigned long f_namemax; /* maximum filename length */
};
```
