.SH SYNOPSIS

#include <libssh2.h>

int
libssh2_session_last_error(LIBSSH2_SESSION *session,

.fi
.SH DESCRIPTION
\fIsession\fP - Session instance as returned by
.BR libssh2_session_init_ex(3)

\fIerrmsg\fP - If not NULL, is populated by reference with the human
readable form of the most recent error message.

\fIerrmsg_len\fP - If not NULL, is populated by reference with the length
of errmsg. (The string is NUL-terminated, so the length is only useful as
an optimization, to avoid calling strlen.)

\fIwant_buf\fP - If set to a non-zero value, "ownership" of the errmsg
buffer will be given to the calling scope. If necessary, the errmsg buffer
will be duplicated.

Determine the most recent error condition and its cause.
.SH RETURN VALUE
Numeric error code corresponding to the the Error Code constants.
