  22 .SH DESCRIPTION
  23 \fIsftp\fP - SFTP instance as returned by
  24 .BR libssh2_sftp_init(3)
  25
  26 \fIpath\fP - Remote filesystem object to create a symlink from or resolve.
  27
  28 \fIpath_len\fP - Length of the name of the remote filesystem object to
  29 create a symlink from or resolve.
  30
  31 \fItarget\fP -
  32 .br
  33 \fBLIBSSH2_SFTP_SYMLINK\fP: Remote filesystem object to link to.
  34 .br
  35 \fBLIBSSH2_SFTP_READLINK\fP: Pre-allocated buffer to resolve symlink target into.
  36 .br
  37 \fBLIBSSH2_SFTP_REALPATH\fP: Pre-allocated buffer to resolve realpath target into.
  38
  39 \fItarget_len\fP - Length of the name of the remote filesystem target object.
  40
  41 \fIlink_type\fP - One of the three previously mentioned constants which
  42 determines the resulting behavior of this function.
  43
  44 .BR libssh2_sftp_symlink(3)
  45 : Create a symbolic link between two filesystem objects.
  46 .br
  47 .BR libssh2_sftp_readlink(3)
  48 : Resolve a symbolic link filesystem object to its next target.
  49 .br
  50 .BR libssh2_sftp_realpath(3)
  51 : Resolve a complex, relative, or symlinked filepath to its effective target.
  52
  53 .SH RETURN VALUE
  54 Return 0 on success or negative on failure.  It returns
  55 LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
  56 LIBSSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.
  57
  58 .SH ERRORS
  59 \fILIBSSH2_ERROR_ALLOC\fP -  An internal memory allocation call failed.
  60
  61 \fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
  62
  63 \fILIBSSH2_ERROR_SOCKET_TIMEOUT\fP -
  64
  65 \fILIBSSH2_ERROR_SFTP_PROTOCOL\fP - An invalid SFTP protocol response was
  66 received on the socket, or an SFTP operation caused an errorcode to
  67 be returned by the server.
