void _fmpq_poly_compose(fmpz * res, fmpz_t den, const fmpz * poly1, const fmpz_t den1, slong len1, const fmpz * poly2, const fmpz_t den2, slong len2)

source

Sets (res, den) to the composition of (poly1, den1, len1) and (poly2, den2, len2), assuming len1, len2 > 0.

Assumes that res has space for (len1 - 1) * (len2 - 1) + 1 coefficients. Does not support aliasing.
