This function returns a temporary sequence collection containing the class names of the collection parts that were used to compose the specified collection.
Format
#include <c$to2.h> long TO2_getCollectionParts (TO2_PID_PTR pid_ptr, TO2_ENV_PTR env_ptr, TO2_PID_PTR retn_pid_ptr);
Normal Return
The normal return is a positive value and the specified TO2_PID_PTR field contains the PID of the temporary sequence collection.
The sequence collection will contain an element in the following format for each part:
struct TO2_partList_element { /* */ long partNumber; /* part number of this part */ u_char partNameLgh; /* length of the part's name */ char partName[ ]; /* object part's class name * };
Error Return
An error return is indicated by a zero. When zero is returned, use the TO2_getErrorCode function to determine the specific error code. For more information, see Error Handling.
The following error codes are common for this function:
TO2_ERROR_ENV
TO2_ERROR_NOT_INIT
TO2_ERROR_PID
Programming Considerations
None.
Examples
The following example copies the part class names for a collection.
#include <c$to2.h> /* Needed for TO2 API Functions */ #include <stdio.h> /* APIs for standard I/O functions */ TO2_ENV_PTR env_ptr; /* Pointer to TO2 environment */ TO2_PID objectPID; /* target object's PID */ TO2_PID collectionPID; /* return area for PID */ TO2_ERR_CODE to2_rc=1; /* return code receiver */ TO2_ERR_TEXT_PTR err_textPtr; /* TO2 error code text pointer */
