// <etymology>
// AipsIOCarray is simply the conventional shorthand for "aips input/output for
// C-style arrays".
// </etymology>
// <synopsis>
// This file declares templated functions to get or put a C-style array
// of any data type from/into AipsIO.
// These functions are similar to the AipsIO functions put, get and getnew,
// but support any data type.
//
// Specializations (using these AipsIO functions) are made for
// the standard data types. These are much more efficient.
// </synopsis>
// <example>
// <srcblock>
// // Write an C-style array of type A into AipsIO.
// // This will first write the number of elements.
// {
// A ap[1000];
// AipsIO io ("file.data", ByteIO::New);
// io.putstart ("some",1);
// putAipsIO (io, uInt(1000), ap);
// io.putend();
// }
// // Read the data back into a preallocated array.
// // First the number of elements have to be read.
// {
// A api[1000];
// uInt n;
// AipsIO io ("file.data");
// io.getstart ("some");
// io >> n;
// getAipsIO (io, n, api);
// }
// // Read the data back into an automatically allocated array.
// // This will also read the number of elements.
// // Delete the allocated array at the end.
// {
// A* api;
// uInt n;
// AipsIO io ("file.data");
// io.getstart ("some");
// getnewAipsIO (io, n, &api);
// delete [] api;
// }
// </srcblock>
// </example>
// <group name=AipsIOCarray>
// Put a C-style array of n elements.
// First the number of elements is put, thereafter all values.
template<class T>
void putAipsIO (AipsIO& aios, uInt n, const T* data);
// Get n elements into an already available C-style array.
// The data buffer must be large enough to hold n values.
template<class T>
void getAipsIO (AipsIO& aios, uInt n, T* data);
// Get elements into a C-style array to be allocated on the heap.
// First the number of elements will be read. The array will be allocated
// by this function and must be freed by the user. Its pointer is returned
// in data. The number of elements is returned in n.
//
// <note>
// Unfortunately the CFront compiler (and maybe others as well) fail to
// overload on <src>T*& data</src> iso. <src>T** data</src>.
// </note>
