Space not enough in the transfer from view to fml

Question

I define that the view's count is 100 and the fml occurence is 100,but when
when i use Fvstof32 to transfer from c structure to fml,the ferror report :NO
SPACE ENOUGH
When i increase the fml occurence ,that can solve this problem .
How i use this to solve this problem without increase the fml occ?
append:
view 's header:
struct INTVAL {                                             
/* View structure for intval information */
     long     mstime[100];          /* null=0 */
     long     smid[100];          /* null=0 */
     float     value[100];          /* null=0.001000 */
fml 's header:
/*     fname     fldid */
#define     MSTIME     ((FLDID32)33554833)     /* number: 401     type: long */
#define     SMID     ((FLDID32)33554834)     /* number: 402     type: long */
#define     VALUE     ((FLDID32)100663699)     /* number: 403     type: float */

I'm not sure what you mean when you say that you define the FML
occurrences as 100. FML does not have a way to limit the number of
occurrences.
Are you referring to the occurrences in the Fneeded32 function? You will
also need "Value" space for the data itself.
Can you call Funused32 right after you tpalloc or Falloc the buffer, and
see what it says? And if you're using Fneeded32, can you call it on its
own, and see what it is returning?
Since your field types are all numeric, they do not need to store field
lengths. I'm assuming that you're on a 32 bit machine, so each of your
data fields takes up 4 bytes. There are another 4 bytes per field for
the Field ID. So you need 300*8 bytes just for the data. Then you need
space for the header and the index. If your index interval is 16, you'll
need around 20 entries.
I would say that 4000 bytes should be adequate, as long as you don't
plan on adding too many fields to the buffer.
