const char* OEGetPDBAtomName(unsigned int idx)
The OEGetPDBAtomName
function converts an OEChem PDB atom name
index, as returned by the OEGetPDBAtomIndex
function, back into
a string representation. Valid indices are specified in OEChem'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 "
.
