Get file system statistics
#include <libssh2.h> #include <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)
These functions provide statvfs(2)-like operations and require [email protected] and [email protected] extension support on the server.
sftp - SFTP instance as returned by libssh2_sftp_init(3)
handle - SFTP File Handle as returned by libssh2_sftp_open_ex(3)
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.
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:
Read-only file system.
Set-user-ID/set-group-ID bits are ignored by exec(3).
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.
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.
Added in libssh2 1.2.6
