示例1: _platform_getExecutable
// static
VFSNode VFSNode::_platform_getExecutable() {
const int PATH_BUFFER_SIZE = 1024;
VString executablePath;
executablePath.preflight(PATH_BUFFER_SIZE);
ssize_t len = ::readlink(PROCESS_LINKPATH, executablePath.buffer(), PATH_BUFFER_SIZE - 1);
if (len == -1) {
throw VStackTraceException(VSystemError(), "VFSNode::_platform_getExecutable: Unable to determine executable path.");
}
executablePath.postflight(len);
return VFSNode(VFSNode::normalizePath(executablePath)); // must supply normalized form to VFSNode below
