NAME

libssh2_sftp_statvfs, libssh2_sftp_fstatvfs - get file system statistics

SYNOPSIS

#include <libssh2.h> lt;libssh2_sftp.h>

int libssh2_sftp_statvfs(LIBSSH2_SFTP *sftp, const char *path,   size_t path_len, LIBSSH2_SFTP_STATVFS *st);

int libssh2_sftp_fstatvfs(LIBSSH2_SFTP_HANDLE *handle,   LIBSSH2_SFTP_STATVFS *st)

DESCRIPTION

These functions provide statvfs(2)-like operations and require statvfs@openssh.com and fstatvfs@openssh.com extension support on the server.

sftp - SFTP instance as returned by libssh2_sftp_init,

handle - SFTP File Handle as returned by libssh2_sftp_open_ex,

path - full path of any file within the mounted file system.

path_len - length of the full path.

st - Pointer to a LIBSSH2_SFTP_STATVFS structure to place file system statistics into.

DATA TYPES

LIBSSH2_SFTP_STATVFS is a typedefed struct that is defined as below

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 */ };

It is unspecified whether all members of the returned struct have meaningful values on all file systems.

The field f_flag is a bit mask. Bits are defined as follows:

LIBSSH2_SFTP_ST_RDONLY

Read-only file system.

LIBSSH2_SFTP_ST_NOSUID

Set-user-ID/set-group-ID bits are ignored by exec(3).

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 isn't really a failure per se.

ERRORS

LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.

LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

LIBSSH2_ERROR_SOCKET_TIMEOUT -

LIBSSH2_ERROR_SFTP_PROTOCOL - An invalid SFTP protocol response was received on the socket, or an SFTP operation caused an errorcode to be returned by the server.

AVAILABILITY

Added in libssh2 1.2.6
