.SH NAME
libssh2_sftp_readdir - read directory data from an SFTP handle
.SH SYNOPSIS
#include <libssh2.h>
#include <libssh2_sftp.h>
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_diropen(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.
\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 -1 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.
