libssh2_sftp_stat_ex - get status about an SFTP file

  #include <libssh2.h>

  int libssh2_sftp_stat_ex(LIBSSH2_SFTP *sftp, const char *path,
                           unsigned int path_len, int stat_type,
                           LIBSSH2_SFTP_ATTRIBUTES *attrs);

sftp - SFTP instance as returned by libssh2_sftp_init(3)

path - Remote filesystem object to stat/lstat/setstat.

path_len - Length of the name of the remote filesystem object to stat/lstat/setstat.

stat_type - One of the three constants specifying the type of stat operation to perform:

LIBSSH2_SFTP_STAT: performs stat(2) operation
LIBSSH2_SFTP_LSTAT: performs lstat(2) operation
LIBSSH2_SFTP_SETSTAT: performs operation to set stat info on file

attrs - Pointer to a LIBSSH2_SFTP_ATTRIBUTES structure to set file metadata from or into depending on the value of stat_type.

Get or Set statbuf type data on a remote filesystem object. When getting statbuf data, libssh2_sftp_stat(3) will follow all symlinks, while libssh2_sftp_lstat(3) will return data about the object encountered, even if that object happens to be a symlink.

The LIBSSH2_SFTP_ATTRIBUTES struct looks like this:

  struct LIBSSH2_SFTP_ATTRIBUTES {
      /* If flags & ATTR_* bit is set, then the value in this struct will be
       * meaningful Otherwise it should be ignored
       */
      unsigned long flags;

      libssh2_uint64_t filesize;
      unsigned long uid;
      unsigned long gid;
      unsigned long permissions;
      unsigned long atime;
      unsigned long mtime;
  };

Returns 0 on success or negative on failure. 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.
