descr2strt (
    const DESCR *descr)

Synopsis

Takes a descriptor prepared by strt2descr() and returns an array of strings pointers, terminated in a null pointer. The array is allocated using the mem_alloc() function. Each string is individually allocated. Thus, to free the string table you must call mem_free() for each entry in the table, except the last one, and then for the table. You can also call strtfree() to destroy the table in a single operation. Returns NULL if there was insufficient memory to allocate the table of strings.
