Function dmd.root.rmem.pureRealloc

Pure variants of C's memory allocation functions malloc, calloc, and realloc and deallocation function free.

extern(C) void* pureRealloc (
  void* ptr,
  ulong size
) pure nothrow @nogc;

UNIX 98 requires that errno be set to ENOMEM upon failure.


// 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.
