| <h4 class="subsection">4.7.3 Passing Parameters by Reference</h4> |
| |
| <p>If the parameter is passed by reference (e.g., Pascal <code>VAR</code> |
| parameters), then the symbol descriptor is ‘<samp>v</samp>’ if it is in the |
| argument list, or ‘<samp>a</samp>’ if it in a register. Other than the fact |
| that these contain the address of the parameter rather than the |
| parameter itself, they are identical to ‘<samp>p</samp>’ and ‘<samp>R</samp>’, |
| respectively. I believe ‘<samp>a</samp>’ is an AIX invention; ‘<samp>v</samp>’ is |
| supported by all stabs-using systems as far as I know. |
