libssh2_channel_open_ex(3) [centos man page]

libssh2_channel_open_ex(3)					  libssh2 manual					libssh2_channel_open_ex(3)

NAME
libssh2_channel_open_ex - establish a generic session channel SYNOPSIS
#include <libssh2.h> LIBSSH2_CHANNEL * libssh2_channel_open_ex(LIBSSH2_SESSION *session, const char *channel_type, unsigned int channel_type_len, unsigned int window_size, unsigned int packet_size, const char *message, unsigned int message_len); LIBSSH2_CHANNEL * libssh2_channel_open_session(session); DESCRIPTION
session - Session instance as returned by libssh2_session_init_ex(3) channel_type - Channel type to open. Typically one of session, direct-tcpip, or tcpip-forward. The SSH2 protocol allowed for additional types including local, custom channel types. channel_type_len - Length of channel_type window_size - Maximum amount of unacknowledged data remote host is allowed to send before receiving an SSH_MSG_CHANNEL_WINDOW_ADJUST packet. packet_size - Maximum number of bytes remote host is allowed to send in a single SSH_MSG_CHANNEL_DATA or SSG_MSG_CHANNEL_EXTENDED_DATA packet. message - Additional data as required by the selected channel_type. message_len - Length of message parameter. Allocate a new channel for exchanging data with the server. This method is typically called through its macroized form: libssh2_chan- nel_open_session(3) or via libssh2_channel_direct_tcpip(3) or libssh2_channel_forward_listen(3) RETURN VALUE
Pointer to a newly allocated LIBSSH2_CHANNEL instance, or NULL on errors. ERRORS
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed. LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket. LIBSSH2_ERROR_CHANNEL_FAILURE - LIBSSH2_ERROR_EAGAIN - Marked for non-blocking I/O but the call would block. SEE ALSO

NAME
libssh2_sftp_stat_ex - get status about an SFTP file SYNOPSIS
#include <libssh2.h> #include <libssh2_sftp.h> int libssh2_sftp_stat_ex(LIBSSH2_SFTP *sftp, const char *path, unsigned int path_len, int stat_type, LIBSSH2_SFTP_ATTRIBUTES *attrs); DESCRIPTION
sftp - SFTP instance as returned by libssh2_sftp_init(3) path - Remote filesystem object to stat/lstat/setstat. path_len - Length of the name of the remote filesystem object to stat/lstat/setstat. stat_type - One of the three constants specifying the type of stat operation to perform: LIBSSH2_SFTP_STAT: performs stat(2) operation LIBSSH2_SFTP_LSTAT: performs lstat(2) operation LIBSSH2_SFTP_SETSTAT: performs operation to set stat info on file attrs - Pointer to a LIBSSH2_SFTP_ATTRIBUTES structure to set file metadata from or into depending on the value of stat_type. Get or Set statbuf type data on a remote filesystem object. When getting statbuf data, libssh2_sftp_stat(3) will follow all symlinks, while libssh2_sftp_lstat(3) will return data about the object encountered, even if that object happens to be a symlink. The LIBSSH2_SFTP_ATTRIBUTES struct looks like this: struct LIBSSH2_SFTP_ATTRIBUTES { /* If flags & ATTR_* bit is set, then the value in this struct will be * meaningful Otherwise it should be ignored */ unsigned long flags; libssh2_uint64_t filesize; unsigned long uid; unsigned long gid; unsigned long permissions; unsigned long atime; unsigned long mtime; }; RETURN VALUE
Returns 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_SOCKET_TIMEOUT - LIBSSH2_ERROR_SFTP_PROTOCOL - An invalid SFTP protocol response was received on the socket, or an SFTP operation caused an errorcode to be returned by the server.
