  Fragmentation functions are one of the key components of the factorisation
theorem used to calculate heavy-flavour hadron production cross sections. The
non-perturbative nature of fragmentation functions necessitates that they are
constrained through experimental measurements, commonly performed in the clean
environments of $\mathrm{e}^{+}\mathrm{e}^{-}$ and ep collisions. However,
recent measurements of charm-hadron transverse-momentum spectra and the ratios
of charmed-hadron abundances in pp collisions have questioned the universality
of fragmentation functions between leptonic and hadronic collision systems in
the baryon sector. In this contribution, we present measurements of
differential observables of heavy-flavour hadrons that also consider the
hadronic density surrounding the hadron. These measurements provide additional
information to the previously reported baryon-to-meson results and allow us
closer access to the charm fragmentation functions. We report the fraction of
longitudinal momentum carried by $\mathrm{D^{0}}$ and $\mathrm{D^{+}_{s}}$
mesons as well as $\Lambda^{+}_\mathrm{c}$ baryons. We also report the
azimuthal correlation distributions between heavy-flavour decay electrons and
charged particles in pp and p--Pb collisions, as well as between
$\Lambda^{+}_\mathrm{c}$ baryons and charged particles in pp collisions, which
provide quantitative access to the angular profile, $p_{\mathrm{T}}$ and
multiplicity distributions of the jets produced by the heavy-quark
fragmentation.
