int libssh2_sftp_readdir(LIBSSH2_SFTP_HANDLE *handle, char *buffer, size_t buffer_maxlen, LIBSSH2_SFTP_ATTRIBUTES *attrs);
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.
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.
Read a block of data from a LIBSSH2_SFTP_HANDLE. This method is modeled after the POSIX readdir(2) however, it uses a variable sized directory entry (filename) buffer and returns statbuf type data in the same call.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
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.
