示例1: it
it('success: A Logger Class can be cast to a C void pointer', () => {
let count = 0
const _logFn = (_level: number,
_target: string,
_message: string,
_modulePath: string,
_file: string,
_line: number) => {
count = count + 1
console.log('level: ' + _level)
console.log('target: ' + _target)
console.log('message: ' + _message)
console.log('modulePath: ' + _modulePath)
console.log('file: ' + _file)
console.log('line: ' + _line)
}
const logFnCb = ffi.Callback('void', ['int', 'string', 'string', 'string', 'string', 'int'], _logFn)
const logger = new Logger()
logger.logFn = logFnCb
const loggerPtr: any = loggerToVoidPtr(logger)
const level = 123
const target = 'target'
const message = 'message'
const modulePath = 'modulePath'
const file = 'file'
const line = 456
loggerFunction(loggerPtr, level, target, message, modulePath, file, line)
