Function dmd.root.rmem.pureCalloc
Pure variants of C's memory allocation functions malloc
, calloc
, and
realloc
and deallocation function free
.
extern(C) void* pureCalloc
(
ulong nmemb,
ulong size
) pure nothrow @nogc @trusted;
UNIX 98 requires that errno be set to ENOMEM upon failure.
https
//linux.die.net/man/3/malloc
However, this is irrelevant for DMD's purposes, and best practice
protocol for using errno is to treat it as an out
parameter, and not
something with state that can be relied on across function calls.
So, we'll ignore it.
