NAME
libssh2_knownhost_writeline - convert a known host to a line for storage SYNOPSIS
#include <libssh2.h> libssh2_knownhost_writeline(LIBSSH2_KNOWNHOSTS *hosts, struct libssh2_knownhost *known, char *buffer, size_t buflen, size_t *outlen, int type); DESCRIPTION
Converts a single known host to a single line of output for storage, using the 'type' output format. known identifies which particular known host buffer points to an allocated buffer buflen is the size of the buffer. See RETURN VALUE about the size. outlen 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! type specifies what file type it is, and LIBSSH2_KNOWNHOST_FILE_OPENSSH is the only currently supported format. 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 outlen size will then hold the requested size. AVAILABILITY
