Synopsis:The concept of union whereby different kinds of data can be manipulated in a single area of storage is allowed only as the solution to certain kinds of problem but caution is urged in its use.
Language:C
Severity Level:4
Category:DECLARATIONS


Description:
Although union is a well-defined concept, it is emphasized that it is the programmer's responsibility to keep track of which type is currently stored in a union as the results are implementation defined if something is stored as one type and extracted as another.
