.SH NAME
|
|
libssh2_userauth_banner - get the server's userauth banner message
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <libssh2.h>
|
|
|
|
int
|
|
libssh2_userauth_banner(LIBSSH2_SESSION *session, char **banner);
|
|
.SH DESCRIPTION
|
|
\fIsession\fP - Session instance as returned by
|
|
.BR libssh2_session_init_ex(3)
|
|
|
|
\fIbanner\fP - Should point to a pointer that gets filled with banner message.
|
|
|
|
After an authentication has been attempted, such as a
|
|
\fBSSH_USERAUTH_NONE\fP request sent by
|
|
.BR libssh2_userauth_list(3) ,
|
|
this function can be called to retrieve the userauth banner sent by
|
|
the server. If no such banner is sent, or if an authentication has not
|
|
yet been attempted, returns LIBSSH2_ERROR_MISSING_USERAUTH_BANNER.
|
|
.SH RETURN VALUE
|
|
On success returns 0 and an UTF-8 NUL-terminated string is stored in the
|
|
\fIbanner\fP. This string is internally managed by libssh2 and will be
|
|
deallocated upon session termination.
|
|
On failure returns
|
|
LIBSSH2_ERROR_MISSING_USERAUTH_BANNER.
