.SH NAME
libssh2_sftp_readdir_ex - read directory data from an SFTP handle
.SH SYNOPSIS
#include <libssh2.h>
#include <libssh2_sftp.h>

int 
libssh2_sftp_readdir_ex(LIBSSH2_SFTP_HANDLE *handle, char *buffer, size_t buffer_maxlen, char *longentry, size_t longentry_maxlen, LIBSSH2_SFTP_ATTRIBUTES *attrs);

int 
libssh2_sftp_readdir(LIBSSH2_SFTP_HANDLE *handle, char *buffer, size_t buffer_maxlen, LIBSSH2_SFTP_ATTRIBUTES *attrs);

.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.

\fIbuffer_maxlen\fP - is the length of buffer in bytes. If the length of the 
filename is longer than the space provided by buffer_maxlen it will be 
truncated to fit.

\fIlongentry\fP - is a pointer to a pre-allocated buffer of at least
\fIlongentry_maxlen\fP bytes to read data into.

\fIlongentry_maxlen\fP - is the length of longentry in bytes. If the length 
of the full directory entry is longer than the space provided by 
longentry_maxlen it will be truncated to fit.

\fIattrs\fP - is a pointer to LIBSSH2_SFTP_ATTRIBUTES storage to populate 
statbuf style data into.

Read a block of data from a LIBSSH2_SFTP_HANDLE. This method is modeled 
after the POSIX 
.BR readdir(2)
however, it uses a variable sized directory entry (filename) buffer and 
returns statbuf type data in the same call.

.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 isn't 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.
