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);
 
 #define libssh2_sftp_readdir(h, b, bl, a)      \
     libssh2_sftp_readdir_ex((h), (b), (bl), NULL, 0, (a))
 
 

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.

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.
