[llvm-dev] Why does LLVm 3.8.0 recognize fputs_unlocked as a vararg function?

[Dipanjan Das via llvm-dev]

Considering F represents the function fputs_unlocked() in an LLVM pass,

 => F->isVarArg() returns true
 => F->getNumParams() returns 0
 => *F returns declare i32 @fputs_unlocked(...)

The signature of fputs_unlocked from man page is:
int fputs_unlocked(const char *s, FILE *stream);

Can anybody explain why fputs_unlocked() is recognized as a vararg method
while it accepts two fixed parameters?
