strange function syntax

I came across this function void int_add( a, b, c) BIGINT *a, *b, *c; { and am confused by the syntax. I assume it is the same as void int_add(BIGINT * a, BIGINT * b, BIGINT * c){
However, as i haven't come across this syntax I wasn't sure.

That's the old K&R style C function syntax. I believe most compilers still support it (willing to be corrected though).

IIRC,

void int_add( a, b, c) BIGINT *a, *b, *c

and

void int_add(BIGINT * a, BIGINT * b, BIGINT * c)

are equivalent.

Note: as mentioned above, it's an old-style C function declaration. C++ compilers will probably tell you that a, b and c are undefined. Visual Studio does provide a clue with the error:

"'{' : missing function header (old-style formal list?)"
