The JagGetSharedValue routine retrieves the value for a specified shared variable and places the value in a buffer. The component object must have retrieved the shared variable reference before executing this routine. The component object must create a buffer in which to copy a value. The buffer must be large enough to hold any value that can be stored in the shared variable. You must specify the buffer (and its size) in which the value is to be copied. The buffer must be large enough to contain the value. If the value is too large for the buffer, JAG_FAIL and the size of the value are returned.
If the value is successfully copied into the buffer, JAG_SUCCEED and the number of bytes copied to the buffer are returned. If *outlen is 0, then there was no value to copy.
