OK dumb question time again: I'm trying to return a pair of fixnums
from a C function.
C_word g2d_glyphs_baseline(struct G2dGlyphs* glyphs)
{
C_word* a = C_alloc(C_SIZEOF_PAIR + 8);
C_return(C_pair (&a, C_int_to_num(&a, 10), C_int_to_num(&a, 256)));
}
or maybe
C_word g2d_glyphs_baseline(struct G2dGlyphs* glyphs)
{
C_word* c_ret = C_alloc(C_SIZEOF_PAIR);
C_word* a = c_ret;
C_int_to_num(&a, 10);
C_int_to_num(&a, 256);
C_return(*c_ret);
}
to be called like this
( (foreign-lambda scheme-object "g2d_glyphs_baseline" g2d-glyph-vector) glyphs)
It compiles and I get weird results at runtime, so obviously am not
building the cons cell correctly.
