Is there a way of making this work with D slices? Can they be
used as C-style pointers?
What about this:
@nogc ubyte[n] rand_bytes(uint n)() {
import core.stdc.stdio;
FILE *fp;
fp = fopen("/dev/urandom", "r");
ubyte[n] buf;
uint bread = 0;
while (bread < n) {
auto toread = n - bread;
auto read = fread(buf[bread .. $].ptr, ubyte.sizeof,
toread, fp);
bread += read;
}
fclose(fp);
return buf;
}
?
Thanks a lot! That works. Did not know about the .ptr for a
slice. Is there any way of making the function with @safe as
well? I get the errors "cannot call @system function
'core.stdc.stdio.fread,fopen,fclose'.
