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_session(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

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 -
