VIX error codes equivalent API in vsphere SDK

Hi Team,

While trying to migrate from VIX to guest operations of vsphere API, I see that there is an equivalent API for running a program on guest, ie, VixVM_RunProgramInGuest ~ StartProgramInGuest. With this API we can fetch exit codes but is there a way to fetch error messages . Also is there an equivalent API for VIX_GetErrorText to fetch SDK error codes smilar to VIX.

Thanks in advance.
