.SH NAME
libssh2_knownhost_writeline - convert a known host to a line for storage
.SH SYNOPSIS
#include <libssh2.h>

libssh2_knownhost_writeline(LIBSSH2_KNOWNHOSTS *hosts,
                            struct libssh2_knownhost *known,
                            char *buffer, size_t buflen,
                            size_t *outlen,
                            int type);
.SH DESCRIPTION
Converts a single known host to a single line of output for storage, using
the 'type' output format.

\fIknown\fP identifies which particular known host

\fIbuffer\fP points to an allocated buffer

\fIbuflen\fP is the size of the \fIbuffer\fP. See RETURN VALUE about the size.

\fIoutlen\fP must be a pointer to a size_t variable that will get the output
length of the stored data chunk. The number does not included the trailing
zero!

\fItype\fP specifies what file type it is, and
\fILIBSSH2_KNOWNHOST_FILE_OPENSSH\fP is the only currently supported
format.
.SH RETURN VALUE
Returns a regular libssh2 error code, where negative values are error codes
and 0 indicates success.

If the provided buffer is deemed too small to fit the data libssh2 wants to
store in it, LIBSSH2_ERROR_BUFFER_TOO_SMALL will be returned. The application
is then advised to call the function again with a larger buffer. The
\fIoutlen\fP size will then hold the requested size.
