/*
*+
* Name:
* datCcopy
* Purpose:
* Copy one structure level
* Language:
* Starlink ANSI C
* Type of Module:
* Library routine
* Invocation:
* datCcopy(const HDSLoc *locator1, const HDSLoc *locator2, const char *name,
HDSLoc **locator3, int *status );
* Arguments:
* locator1 = const HDSLoc * (Given)
* Object locator to copy.
* locator2 = const HDSLoc * (Given)
* Locator of structure to receive copy of object.
* name = const char * (Given)
* Name of object when copied into structure.
* locator3 = HDSLoc ** (Returned)
* Locator of newly copied component.
* status = int* (Given and Returned)
* Pointer to global status.
* Description:
* Copy an object into a structure and give the new component the
* specified name. If the source object is a structure, a new structure
* of the same type and shape is created but the content of the
* original structure is not copied.
* Authors:
* TIMJ: Tim Jenness (Cornell)
* {enter_new_authors_here}
* History:
* 2014-10-14 (TIMJ):
* Initial version
* 2014-10-29 (TIMJ):
* Enable copying of an undefined primitive object.
