This declaration does not match the definition you give later.

as diagnosed by the compiler!

Above, you declared it as returning void and taking a char *.  You
can't lie to the compiler and get away with it for long.  You need to
#include the header that declares parseargs in the file source that
defines it as well.  That way, you get a check that the declaration
matches the definition.  If the definition is in the same file, you
still need to make sure the two match up.
