DESCRIPTION

22       These  functions  provide  statvfs(2)-like   operations   and   require
23       statvfs@openssh.com  and  fstatvfs@openssh.com extension support on the
24       server.
25
26       sftp - SFTP instance as returned by libssh2_sftp_init(3)
27
28       handle - SFTP File Handle as returned by libssh2_sftp_open_ex(3)
29
30       path - full path of any file within the mounted file system.
31
32       path_len - length of the full path.
33
34       st - Pointer to a LIBSSH2_SFTP_STATVFS structure to place  file  system
35       statistics into.

DATA TYPES

39       LIBSSH2_SFTP_STATVFS is a typedefed struct that is defined as below
40
41       struct _LIBSSH2_SFTP_STATVFS {
42           libssh2_uint64_t  f_bsize;    /* file system block size */
43           libssh2_uint64_t  f_frsize;   /* fragment size */
44           libssh2_uint64_t  f_blocks;   /* size of fs in f_frsize units */
45           libssh2_uint64_t  f_bfree;    /* # free blocks */
46           libssh2_uint64_t  f_bavail;   /* # free blocks for non-root */
47           libssh2_uint64_t  f_files;    /* # inodes */
48           libssh2_uint64_t  f_ffree;    /* # free inodes */
49           libssh2_uint64_t  f_favail;   /* # free inodes for non-root */
50           libssh2_uint64_t  f_fsid;     /* file system ID */
51           libssh2_uint64_t  f_flag;     /* mount flags */
52           libssh2_uint64_t  f_namemax;  /* maximum filename length */
53       };
54
55       It is unspecified whether all members of the returned struct have mean‐
56       ingful values on all file systems.
57
58       The field f_flag is a bit mask. Bits are defined as follows:
59
60       LIBSSH2_SFTP_ST_RDONLY
61              Read-only file system.
62
63       LIBSSH2_SFTP_ST_NOSUID
64              Set-user-ID/set-group-ID bits are ignored by exec(3).
65
66

RETURN VALUE

68       Returns 0 on success or negative on failure. If  used  in  non-blocking
69       mode,  it  returns  LIBSSH2_ERROR_EAGAIN when it would otherwise block.
70       While LIBSSH2_ERROR_EAGAIN is a negative  number,  it  isn't  really  a
71       failure per se.
72

ERRORS

74       LIBSSH2_ERROR_ALLOC -  An internal memory allocation call failed.
75
76       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
77
78       LIBSSH2_ERROR_SOCKET_TIMEOUT -
79
80       LIBSSH2_ERROR_SFTP_PROTOCOL  -  An  invalid  SFTP protocol response was
81       received on the socket, or an SFTP operation caused an errorcode to  be
82       returned by the server.
