libssh2_scp_send64: added to API to provide large file transfers

Browse Source 
The previously existing libssh2_scp_send_ex() function has no way
to send files that are larger than 'size_t' which on 32bit
systems mean 4GB. This new API uses a libssh2_int64_t type and
should thus on most modern systems be able to send enormous
files.

.SH NAME
libssh2_scp_send64 - Send a file via SCP
.SH SYNOPSIS
.nf
#include <libssh2.h>
LIBSSH2_CHANNEL *
libssh2_scp_send64(LIBSSH2_SESSION *session, const char *path, int mode,
libssh2_uint64_t size, time_t mtime, time_t atime);
.SH DESCRIPTION
\fIsession\fP - Session instance as returned by
.BR libssh2_session_init_ex(3)
\fIpath\fP - Full path and filename of file to transfer to. That is the remote
file name.
\fImode\fP - File access mode to create file with
\fIsize\fP - Size of file being transmitted (Must be known ahead of
time). Note that this needs to be passed on as variable type
libssh2_uint64_t. This type is 64 bit on modern operating systems and
compilers.
\fImtime\fP - mtime to assign to file being created
\fIatime\fP - atime to assign to file being created (Set this and
mtime to zero to instruct remote host to use current time).
Send a file to the remote host via SCP.
.SH RETURN VALUE
Pointer to a newly allocated LIBSSH2_CHANNEL instance, or NULL on errors.
.SH ERRORS
\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
\fILIBSSH2_ERROR_SCP_PROTOCOL\fP -
\fILIBSSH2_ERROR_EAGAIN\fP - Marked for non-blocking I/O but the call would
block.
.SH AVAILABILITY
This function was added in libssh2 1.2.6 and is meant to replace the former
\fIlibssh2_scp_send_ex(3)\fP function.
