Re: Copying fread behaviour on char array

Hello everybody I want to create a routine that mimic the fread

I wrote

size_t fread_char(void* buf, size_t sz, size_t n, char* string_source)
{

memcpy(buf, string_source, sz*n);
string_source += n*sz;

return n;
}

When I leave the routine the string_source doesn't change its value, it
seems that the operation string_source += n*sz; has not been performed

Hint : Use

size_t fread_char(void* buf, size_t sz, size_t n, char**
string_source)

.
