NAME

       libssh2_sftp_symlink_ex - read or set a symbolic link

SYNOPSIS

       #include <libssh2.h>
       #include <libssh2_sftp.h>

       int
       libssh2_sftp_symlink_ex(LIBSSH2_SFTP *sftp, const char *path,
			       unsigned int path_len, char *target,
			       unsigned int target_len, int link_type);

DESCRIPTION

       Create a symlink or read out symlink information from the remote side.

       sftp - SFTP instance as returned by libssh2_sftp_init(3)

       path - Remote filesystem object to create a symlink from or resolve.

       path_len - Length of the name of the remote filesystem object to create a symlink from or resolve.

       target - a pointer to a buffer. The buffer has different uses depending what the link_type argument is set to.
       LIBSSH2_SFTP_SYMLINK: Remote filesystem object to link to.
       LIBSSH2_SFTP_READLINK: Pre-allocated buffer to resolve symlink target into.
       LIBSSH2_SFTP_REALPATH: Pre-allocated buffer to resolve realpath target into.

       target_len - Length of the name of the remote filesystem target object.

       link_type - One of the three previously mentioned constants which determines the resulting behavior of this function.

       These are convenience macros:

       libssh2_sftp_symlink(3) : Create a symbolic link between two filesystem objects.
       libssh2_sftp_readlink(3) : Resolve a symbolic link filesystem object to its next target.
       libssh2_sftp_realpath(3) : Resolve a complex, relative, or symlinked filepath to its effective target.

RETURN VALUE

       When using LIBSSH2_SFTP_SYMLINK, this funtion returns 0 on success or negative on failure.

       When using LIBSSH2_SFTP_READLINK or LIBSSH2_SFTP_REALPATH, it returns the number of bytes it copied to the target buffer (not including 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.

       From 1.2.8, LIBSSH2_ERROR_BUFFER_TOO_SMALL is returned if the given 'target' buffer is too small to fit the requested object name.

BUG

       Passing	in  a  too small buffer 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.

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 opera-
       tion 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 lon-
       gentry_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 LIB-
       SSH2_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.
