.SH NAME
|
|
libssh2_sftp_readdir_ex - read directory data from an SFTP handle
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#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);
|

libssh2_sftp_readdir_ex((h), (b), (bl), NULL, 0, (a))
|
|
.SH DESCRIPTION
|
|
Reads a block of data from a LIBSSH2_SFTP_HANDLE and returns file entry
|
|
information for the next entry, if any.
|
|
|
|
\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. The format of the `longname'
|
|
field is unspecified by SFTP protocol. It MUST be suitable for use in the
|
|
output of a directory listing command (in fact, the recommended operation for
|
|
a directory listing command is to simply display this data).
|
|
|
|
\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
|
|
\fIlongentry_maxlen\fP 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 (not counting the terminating
|
|
zero), 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.
