.SH NAME
libssh2_sftp_readdirnb - read directory data from an SFTP handle non-blocking
.SH SYNOPSIS
#include <libssh2.h>
#include <libssh2_sftp.h>
int libssh2_sftp_readdirnb(LIBSSH2_SFTP_HANDLE *handle, char *buffer,
size_t buffer_maxlen, LIBSSH2_SFTP_ATTRIBUTES *attrs);
.SH DESCRIPTION
Read a block of data from a LIBSSH2_SFTP_HANDLE non-blocking. This method is
modeled after the POSIX \fIreaddir(3)\fP however, it uses a variable sized
directory entry (filename) buffer and returns statbuf type data in the same
call.
\fIhandle\fP is the SFTP File Handle as returned by
\fIlibssh2_sftp_diropen(3)\fP.
\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.
.SH RETURN VALUE
Number of bytes actually populated into buffer, or negative on failure. It
returns LIBSSH2CHANNEL_EAGAIN when it would otherwise block. While
LIBSSH2CHANNEL_EAGAIN is a negative number, it isn't really a failure per se.
