This function returns a sequence collection of the information about the specified class.
Format
#include <c$to2.h> long TO2_getClassInfo ( TO2_PID_PTR pid_ptr, TO2_ENV_PTR env_ptr, const long *class_nameLength, const char class_name[TO2_MAX_CLASS_NAME]);
Normal Return
The normal return is a positive value.
Error Return
An error return is indicated by a zero. When zero is returned, use the TO2_getErrorCode function to determine the specific error code. For more information, see Error Handling.
The following error code is common for this function:
TO2_ERROR_NO_ROOM
Programming Considerations
None.
Examples
The following example retrieves the PID for the class name indicated.
#include <c$to2.h> /* Needed for TO2 API functions */ #include <stdio.h> /* APIs for standard I/O functions */ long err_code; TO2_ENV_PTR env_ptr; /* Pointer to TO2 environment */ TO2_PID collect; char *class_name; long classname_length;
