If the second argument ** points to a NULL, then the memory is allocated for the creation ** of the structure element. Otherwise, no new memory is ** allocated and the structure element is replaced in place. ** This scheme requires that the calling routine ensure ** that there is sufficient memory already allocated for replacing ** in place. ** ** To support this scheme, parse routine writers must calculate ** the amount of memory required to store the element in server ** native format before allocating it, and pass this number of ** bytes as the 3rd argument to the below macro GET_DD_STORAGE. ** Then the parse routine can be put in both the parse and ** replace tables as the entry for handling the OC. ** ** Note that there are 3 exceptions to this symmetry: ** LightState ** SOFAS ** NurbSurfaces ** ** For each of these, there are separate parse and replace ** routines. ** ** For any OC that follows the above scheme, the corresponding ** entry in the destroy table can be the default (destroyOC_PEX), ** since memory allocation is therefore in one chunk. If the ** coder of a parse routine cannot write the routine so that all ** of the memory is allocated at once, then they must also write ** a special destroy routine for this element (to ensure no ** memory leakage). ** ** Coders of parsing routines must also provide corresponding ** copy and inquire routines (see miCopy.c and miInquire.c). **/ #if (__STDC__ && !defined(UNIXCPP)) || defined(ANSICPP) #define CAT(a,b) a##b #else #define CAT(a,b) a/**/b #endif #define OC_PARSER_FUNC_HEADER(suffix) \ ddpex2rtn CAT(parse,suffix)(pPEXOC, ppExecuteOC)\ ddElementInfo *pPEXOC;
