# Synopsis

PDX_MSGT mda_CopyFromOList(long option, void *ent, OLM_LIST *list, MDA_COUNT *count, void *ptr)

# Purpose

# Description

The contents of the specified object list will be copied to an entity field. The list will be copied in first to last order. The number of list elements copied will be stored in the count argument.

If the number of elements in the list is 0, no memory will be allocated, the count will be set to 0, a NULL pointer will be stored in ptr, and a value of MDA_NOERR will be returned.
