I am trying to learn software reverse engineering with Ghidra, though I have never used Visual Studio Compilers or the C runtime (CRT). I have a piece of decompiled C code:

<typeName> <functionName>(<typeName>)
{
  ulonglong myVar;

  __security_init_cookie();

  myVar = __scrt_initialize_crt(1);

  if ((char)myVar == '\0') {
    // some code
  }
}

where ulonglong is Unsigned Long Long Integer with a length of 8 according to Ghidra Decompiler.

I tried reading the __security_init_cookie() documentation here, to no avail. And there is not much documentation about the __scrt_initialize_crt() function.

I would appreciate it if you could help me understand what the above piece of code does.

P.S. More information about the __scrt_initialize_crt() function here, and its input type __scrt_module_type here.

P.S.1. More information about the __scrt_initialize_crt() function here, and its input type __scrt_module_type here.

P.S.2. I posted a follow-up question here on SO.
