Need some help with this
Author
What is wrong with this. It crashes the program. I want to read data into a structure or variable:
assume:
a FILE is open called "data"
a "datafile" class exists as df
--------------------
BITMAPFILEHEADER df;
df->readdat(&bminfo,sizeof(BITMAPFILEHEADER));
-----------------------
void datafile::readdat(void *buf, unsigned int len){
fread(&buf,len,1,data);
}
void datafile::readdat(void *buf, unsigned int len){fread(&buf,len,1,data);} shoule be
void datafile::readdat(void *buf, unsigned int len){fread(buf,len,1,data);} (Note the lack of the &)
Edit: Just tested it. Strange, MSVC doesn't catch the error of casting a void** to a void* ...

Yes. But the second time I call it, it crashes. The data reads fine the first time.
