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.
