Good question, but I don't think so. The first few lines of assembly
from this function seem to read three arguments you see:

  44b360:    53                       push   %rbx
  44b361:    41 54                    push   %r12
  44b363:    41 55                    push   %r13
  44b365:    48 89 fb                 mov    %rdi,%rbx        <-- first
argument, %rdi
  44b368:    41 89 f4                 mov    %esi,%r12d       <-- second
argument, %rsi
  44b36b:    49 89 d5                 mov    %rdx,%r13        <-- third
argument, %rdx

What I forgot to mention was that this is on a x86_64 architecture, so I
based myself on the table found at
http://wiki.osdev.org/Calling_Conventions .
