.SH NAME
libssh2_session_last_error - get the most recent error
.SH SYNOPSIS
#include <libssh2.h>

int
libssh2_session_last_error(LIBSSH2_SESSION *session, char **errmsg, int *errmsg_len, int want_buf);

.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.
