| .SH NAME |
| libssh2_sftp_symlink_ex - read or set a symbolic link |
| .SH 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); |
| |
| .SH DESCRIPTION |
| \fIsftp\fP - SFTP instance as returned by |
| .BR libssh2_sftp_init(3) |
| |
| \fIpath\fP - Remote filesystem object to create a symlink from or resolve. |
| |
| \fIpath_len\fP - Length of the name of the remote filesystem object to |
| create a symlink from or resolve. |
| |
| \fItarget\fP - |
| .br |
| \fBLIBSSH2_SFTP_SYMLINK\fP: Remote filesystem object to link to. |
| .br |
| \fBLIBSSH2_SFTP_READLINK\fP: Pre-allocated buffer to resolve symlink target into. |
| .br |
| \fBLIBSSH2_SFTP_REALPATH\fP: Pre-allocated buffer to resolve realpath target into. |
| |
| \fItarget_len\fP - Length of the name of the remote filesystem target object. |
| |
| \fIlink_type\fP - One of the three previously mentioned constants which |
| determines the resulting behavior of this function. |
| |
| .BR libssh2_sftp_symlink(3) |
| : Create a symbolic link between two filesystem objects. |
| .br |
| .BR libssh2_sftp_readlink(3) |
| : Resolve a symbolic link filesystem object to its next target. |
| .br |
| .BR libssh2_sftp_realpath(3) |
| : Resolve a complex, relative, or symlinked filepath to its effective target. |
| |
| .SH 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. |
| |
| .SH ERRORS |
| \fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed. |
| |
| \fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket. |
| |
| \fILIBSSH2_ERROR_SOCKET_TIMEOUT\fP - |
| |
| \fILIBSSH2_ERROR_SFTP_PROTOCOL\fP - An invalid SFTP protocol response was |
| received on the socket, or an SFTP operation caused an errorcode to |
| be returned by the server. |
