| ERROR | formal parameter VARCHARs should be declared as pointers |
| CAUSE | Many C compilers allow structures to be passed to and returned from functions. Although a VARCHAR is implemented as a C struct, VARCHARs must be passed to a function as pointers. |
| ACTION | Take the address of a VARCHAR when it is passed to a function. See the example in the section Referencing VARCHAR Variables in the Programmers Guide to the Oracle Precompilers. |
