OpenSSH: SFTP X SCP
Hi all,
I'm implementing some updates to my scripts that are now using ftp command.
I was thinking about replace it by SFTP.
Now I see that SCP does basically the same that SFTP.
So... what are the differences between them?
Thanks in advance...

Hello friends! :)
I'm very interested in how if one is able to list active and or previous scp connections via OpenSSH to *BSD, GNU machines.
Kinda like "last" does, without being forced to look in logfiles or netstat.
Anyone aware of any such functionallity?
Cheers!

libssh2_sftp_read
libssh2_sftp_read(3) libssh2 manual libssh2_sftp_read(3)
NAME
libssh2_sftp_read - read data from an SFTP handle
SYNOPSIS
#include <libssh2.h> #include <libssh2_sftp.h>
ssize_t libssh2_sftp_read(LIBSSH2_SFTP_HANDLE *handle, char *buffer, size_t buffer_maxlen);
DESCRIPTION
handle is the SFTP File Handle as returned by libssh2_sftp_open_ex(3)
buffer is a pointer to a pre-allocated buffer of at least
buffer_maxlen bytes to read data into.
Reads a block of data from an LIBSSH2_SFTP_HANDLE. This method is modelled after the POSIX read(2) function and uses the same calling
semantics. libssh2_sftp_read(3) will attempt to read as much as possible however it may not fill all of buffer if the file pointer reaches
the end or if further reads would cause the socket to block.
RETURN VALUE
Number of bytes actually populated into buffer, 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.
