NAME

       libssh2_sftp_readdir_ex - read directory data from an SFTP handle

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);

DESCRIPTION

       Reads  a  block  of data from a LIBSSH2_SFTP_HANDLE and returns file entry information for
       the next entry, if any.

       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.

       buffer_maxlen  - 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.

       longentry - is a pointer to a pre-allocated buffer of at least longentry_maxlen  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).

       longentry_maxlen  -  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.

       attrs  -  is  a  pointer to LIBSSH2_SFTP_ATTRIBUTES storage to populate statbuf style data
       into.

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.

BUG

       Passing in a too small buffer for 'buffer' or 'longentry' when receiving data only results
       in libssh2 1.2.7 or earlier to not copy the entire data amount, and it is not possible for
       the application to tell when it happens!

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.

       From  1.2.8,  LIBSSH2_ERROR_BUFFER_TOO_SMALL  is  returned if any of the given 'buffer' or
       'longentry' buffers are too small to fit the requested object name.
