Studies of open-charm hadron production in pp and \pPb collisions areperformed by the ALICE Collaboration at the LHC to investigate charm-quarkhadronization mechanisms. Recent measurements of charm meson (${\rm D^0}$,${\rm D^+}$, ${\rm D^+_{\rm s}}$, and ${\rm D^{*+}}$) and baryon($\Lambda^+_{\rm c}$, $\Xi^{0,+}_{\rm c}$, $\Sigma^{0,++}_{\rm c}$, and$\Omega^0_{\rm c}$) production in pp collisions at $\sqrt{s}$ = 5.02 TeV and$\sqrt{s}$ = 13 TeV allow the determination of the charm cross section and thefragmentation fractions at $\sqrt{s}$ = 5.02 TeV with unprecedented precision.The measurements show that the fragmentation fractions significantly differfrom the ones measured in ${\rm e^+e^-}$ and \ep collisions. This highlightspossible differences in the hadronization process between electron inducedcollisions and pp collisions at the LHC. \\ Furthermore, the first measurementof the baryon-to-meson yield ratio $\Lambda^+_{\rm c}/{\rm D^0}$, down to$p_{\rm T}=0$ in pp and \pPb collisions will be discussed. In p--Pb collisionsa modification of the hadronization mechanisms could be present due to coldnuclear matter effects and collective phenomena. A systematic comparisonbetween data and model calculations will help to understand charm quarkhadronization in pp and p--Pb collisions.
