C File reading and writing
 

hi

I was writing an application where i need to write text to a file whose size is determined at runtime.

I am familiar with this

struct book
{
int num;
char msg[FIXED_SIZE];
};

Then performing fread and fwrite.
But what i require is char *msg rather than msg[FIXED_SIZE].

Could anyone give me some reference or a snippet of how to do this.

Thank You

I don't get exactly your point

your two variables message are equivalent: msg[0]=*msg

Sorry for this poor help, but I'm not fully acquainted with de details of fwrite but I guess that typecasting would be sufficient.
