Qt: Write Struct to File

Question

I\'m struggling with writing a struct to a file via QFile in Qt.

typedef struct {
    uint32_t timestamp;
    uint32_t recordType;
             


        

Answer 1

Much simpler:

assuming your structure 'DataPacket'

void MyClass::write()
{
QFile out(FILE_PATH_NAME);
out.open(QIODevice::WriteOnly);
out.write((const char *)DataPacket,sizeof(DataPacket));
out.close();
}

void MyClass::read()
{
QFile in(FILE_PATH_NAME);
in.open(QIODevice::ReadOnly);
in.read((const char *)DataPacket,sizeof(DataPacket));
in.close();
}
