i have a function, GetCPUType(), that returns a local (but static)
string. this works from main():
char buf[BUFFERSZ];
strcpy(buf, GetCPUType(proc_cpu));
printf("CPU Type: %s", buf);
this doesn't (it prints garbage):
printf("CPU Type: %s", GetCPUType(proc_cpu));
the function looks like:
char *GetCPUType(const char *file)
{
static char *ptr;
/* do stuff with ptr */
return ptr;
}
what's the difference between putting ptr into a buffer and printing the
buffer vs. printfing the pointer to a string directly? ptr ends with
\0.
