It's always _technically_ _possible_ thanks to the calling
convention (i.e., on the low level), but it's not a _valid_
ISO _C_ to call functions with different arguments than it
has, so the compiler rejects it.  Do
typedef void (*Foo)(const char*, const char*, const char*);
Typecast &puts to Foo and you can call it with three
arguments.
