val byteArray = str.toByteArray(Charsets.UTF_8) val paddedByteArray = byteArray.copyOf(10) { 0 } 在上述代码中,我们首先定义了一个字符串str,然后使用toByteArray()函数将其转换为字节数组byteArray,并指定字符集为UTF-8。接下来,我们使用copyOf()函数将字节数组byteArray复制到一个长度为10的...
val copiedStringFromC = buf.stringFromUtf8() println("Message from C: $copiedStringFromC") } 首先,需要有一个原生的指针来传递这个 C 函数。使用usePinned扩展函数来临时固定字节数组的原生内存地址。该 C 函数填充了带数据的字节数组。使用另一个扩展函数ByteArray.stringFromUtf8()将字节数组转换为一个 ...

to fix that, in 1.3.50 we’ve added a new function to deal with NULL-terminated UTF-8 strings easily. TheByteArray.toKString()function (from thekotlinx.cinteroppackage) can be used to turn a NULL-terminated UTF-8 string into a Kotlin string. You can pass start and end indices to ...
