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

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_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

ERRORS

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.
