const char *OEGetPDBAtomName(unsigned int idx)

Converts an OEChem TK PDB atom name index, as returned by the OEGetPDBAtomIndex function, back into a string representation. Valid indices are specified in OEChem TK’s OEPDBAtomName namespace.

A NULL pointer, (char*)0, is returned for invalid or unrecognized argument values. All other returned string constants are guaranteed to be four characters long. For example, the input value OEPDBAtomName.CA returns the string value " CA ".
