.SH NAME
|
|
libssh2_sftp_read - read data from an SFTP handle
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <libssh2.h>
|
|
#include <libssh2_sftp.h>
|
|
|
|
ssize_t

|
libssh2_sftp_read(LIBSSH2_SFTP_HANDLE *handle,
|
|
char *buffer, size_t buffer_maxlen);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
\fIhandle\fP is the SFTP File Handle as returned by
|
|
.BR libssh2_sftp_open_ex(3)
|
|
|
|
\fIbuffer\fP is a pointer to a pre-allocated buffer of at least
|
|
|
|
\fIbuffer_maxlen\fP bytes to read data into.
|
|
|
|
Reads a block of data from an LIBSSH2_SFTP_HANDLE. This method is modelled
|
|
after the POSIX
|
|
.BR read(2)
|
|
function and uses the same calling semantics.
|
|
.BR 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.
|
|
.SH 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 is not really a failure per se.
|
|
.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.
