libssh2_sftp_statvfs, libssh2_sftp_fstatvfs - get file system statistics

.SH DESCRIPTION
|
|
These functions provide statvfs(2)-like operations and require
|
|
statvfs@openssh.com and fstatvfs@openssh.com extension support on the server.
|
|
|
|
\fIsftp\fP - SFTP instance as returned by
|
|
.BR libssh2_sftp_init(3)
|
|
|
|
\fIhandle\fP - SFTP File Handle as returned by
|
|
.BR libssh2_sftp_open_ex(3)
|
|
|
|
\fIpath\fP - full path of any file within the mounted file system.
|
|
|
|
\fIpath_len\fP - length of the full path.
|
|
|
|
\fIst\fP - Pointer to a LIBSSH2_SFTP_STATVFS structure to place file system
|
|
statistics into.
|
|
.SH DATA TYPES
|
|
LIBSSH2_SFTP_STATVFS is a typedefed struct that is defined as below
|
|
|
|
.nf
|
|
struct _LIBSSH2_SFTP_STATVFS {
|
|
libssh2_uint64_t f_bsize; /* file system block size */
|
|
libssh2_uint64_t f_frsize; /* fragment size */
|
|
libssh2_uint64_t f_blocks; /* size of fs in f_frsize units */
|
|
libssh2_uint64_t f_bfree; /* # free blocks */
|
|
libssh2_uint64_t f_bavail; /* # free blocks for non-root */
|
|
libssh2_uint64_t f_files; /* # inodes */
|
|
libssh2_uint64_t f_ffree; /* # free inodes */
|
|
libssh2_uint64_t f_favail; /* # free inodes for non-root */
|
|
libssh2_uint64_t f_fsid; /* file system ID */
|
|
libssh2_uint64_t f_flag; /* mount flags */
|
|
libssh2_uint64_t f_namemax; /* maximum filename length */
|
|
};
|
|
.fi
|
|
|
|
It is unspecified whether all members of the returned struct have meaningful
|
|
values on all file systems.
|
|
|
|
The field \fIf_flag\fP is a bit mask. Bits are defined as follows:
|
|
.IP LIBSSH2_SFTP_ST_RDONLY
|
|
Read-only file system.
|
|
.IP LIBSSH2_SFTP_ST_NOSUID
|
|
Set-user-ID/set-group-ID bits are ignored by \fBexec\fP(3).
|
|
.SH RETURN VALUE
|
|
Returns 0 on success or negative on failure. If used in non-blocking mode, it
|
|
returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
|
|
LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
|
|
.SH ERRORS
|
|
\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
|
|
|
|
\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
|
|
|
|
\fILIBSSH2_ERROR_SOCKET_TIMEOUT\fP -
|
|
|
|
\fILIBSSH2_ERROR_SFTP_PROTOCOL\fP - An invalid SFTP protocol response was
|
|
received on the socket, or an SFTP operation caused an errorcode to be returned
|
|
by the server.
