Function
Determines whether an Object can be converted to a list of strings and, if so, extracts the nth one from it.
Syntax
#include <dx/dx.h>
Object DXExtractNthString(Object o, int n, char **cp)
Functional Details
If Object o contains at least an nth string (where n is a zero-based index), this routine extracts it and places a pointer to its first character in *cp.
Strings may be extracted from:
Return Value
Returns o and sets cp if the nth string can be extracted from o; otherwise, returns NULL without setting an error code.
