libssh2_channel_setenv_ex - set an environment variable on the channel
SYNOPSIS
#include <libssh2.h>
int libssh2_channel_setenv_ex(LIBSSH2_CHANNEL *channel, char *varname, unsigned int varname_len, const char *value, unsigned int
value_len);
int libssh2_channel_setenv(LIBSSH2_CHANNEL *channel, char *varname, const char *value);
DESCRIPTION
channel - Previously opened channel instance such as returned by libssh2_channel_open_ex(3)
varname - Name of environment variable to set on the remote channel instance.
varname_len - Length of passed varname parameter.
value - Value to set varname to.
value_len - Length of value parameter.
Set an environment variable in the remote channel's process space. Note that this does not make sense for all channel types and may be
ignored by the server despite returning success.
RETURN VALUE
Return 0 on success or negative on failure. It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
negative number, it isn't really a failure per se.
ERRORS
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_CHANNEL_REQUEST_DENIED -

libssh2_channel_x11_req_ex - request an X11 forwarding channel
SYNOPSIS
#include <libssh2.h>
int libssh2_channel_x11_req_ex(LIBSSH2_CHANNEL *channel, int single_connection, const char *auth_proto, const char *auth_cookie, int
screen_number);
int libssh2_channel_x11_req(LIBSSH2_CHANNEL *channel, int screen_number);
DESCRIPTION
channel - Previously opened channel instance such as returned by libssh2_channel_open_ex(3)
single_connection - non-zero to only forward a single connection.
auth_proto - X11 authentication protocol to use
auth_cookie - the cookie (hexadecimal encoded).
screen_number - the XLL screen to forward
Request an X11 forwarding on channel. To use X11 forwarding, libssh2_session_callback_set(3) must first be called to set LIBSSH2_CALL-
BACK_X11. This callback will be invoked when the remote host accepts the X11 forwarding.
RETURN VALUE
Return 0 on success or negative on failure. It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
negative number, it isn't really a failure per se.

Of course I can use:
dummy=${!parameter}
${#dummy}
but that's a... (0 Replies)
I want to save the contents of a variable to a file. How can that be achieved?
I have tried with:
echo $varname > textfile.txt
but for some reason it does not print anything. (1 Reply)
after some years of pause, im returning to c.
char *varname = "asd";
int *number = 4;
the above code is wrong, because its assigning a value to an unreserved space, or because its changing the address the pointer is pointing ?
thanks for the replys!! (3 Replies)
