.SH NAME
|
|
libssh2_sftp_write - write SFTP data
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <libssh2.h>
|
|
#include <libssh2_sftp.h>
|
|
|
|
ssize_t libssh2_sftp_write(LIBSSH2_SFTP_HANDLE *handle,
|
|
const char *buffer,
|
|
size_t count);
|
|
.SH DESCRIPTION
|
|
\fBlibssh2_sftp_write(3)\fP writes a block of data to the SFTP server. This
|
|
method is modeled after the POSIX write() function and uses the same calling
|
|
semantics.
|
|
|
|
\fIhandle\fP - SFTP file handle as returned by \fIlibssh2_sftp_open_ex(3)\fP.
|
|
|
|
\fIbuffer\fP - points to the data to send off.
|
|
|
|
\fIcount\fP - Number of bytes from 'buffer' to write. Note that it may not be
|
|
possible to write all bytes as requested.
|
|
|
|
\fIlibssh2_sftp_handle(3)\fP will use as much as possible of the buffer and
|
|
put it into a single SFTP protocol packet. This means that to get maximum
|
|
performance when sending larger files, you should try to always pass in at
|
|
least 32K of data to this function.
|
|
.SH RETURN VALUE
|
|
Actual number of bytes written or negative on failure.
|
|
|
|
If used in non-blocking mode, 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.
|
|
|
|
If this function returns 0 (zero) it should not be considered an error, but
|
|
simply that there was no error but yet no payload data got sent to the other
|
|
end.
|
|
.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_SOCKET_TIMEOUT\fP -
|
|
|
|
\fILIBSSH2_ERROR_SFTP_PROTOCOL\fP - An invalid SFTP protocol response was
|
|
received on the socket, or an SFTP operation caused an errorcode to
|
|
be returned by the server.
