fix: add missing parameter types to function declarations

Some functions were declared without parameters in header files,
despite their implementations specifying arguments. This mismatch
is deprecated in all versions of C and is disallowed in C23.

This change updates the declarations to match their definitions,
ensuring compatibility with C standards, avoiding potential
undefined behavior, and improving support in tools and editors.
