libssh2 manual libssh2_sftp_symlink_ex(3ssh2) 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 function 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 lib- ssh2 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.
