How do I read binary data files ?

[IGSSoft]

I need convert the read data in int, int8, int16 or short, int32 or long and int64.
I use

int fgetc( FILE *stream );
wint_t fgetwc( FILE *stream );



but this function only read int8 and short. Regard

The way I normally do it is use the fstream class as follows:


fstream fileStrm;

fileStrm.open(czFileName,ios::in | ios:ut | ios::binary);

int myInt;
float myFloat;
short myShort;

fileStrm.read((char*)&myInt,sizeof(myInt));
fileStrm.read((char*)&myFloat,sizeof(myFloat));
fileStrm.read((char*)&myShort,sizeof(myShort));




If you look up the documentation for fstream::read, the arguments are very straight forward.

Hope that helps.

Hey,
Can we use >> and << to input and output a
binary file?
Thanks.
