libssh2_sftp_symlink_ex(3)

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); int libssh2_sftp_symlink(LIBSSH2_SFTP *sftp, const char *path, char *target); int libssh2_sftp_readlink(LIBSSH2_SFTP *sftp, const char *path, char *target, unsigned int target_len); int libssh2_sftp_realpath(LIBSSH2_SFTP *sftp, const char *path, char *target, unsigned int target_len);

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 -
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. 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
Return 0 on success 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.
