The NVI_Buf->Length_NVI is 10, it is exactly the same as the
fp->null_map_len. So I don't think the memory is getting corrupted?
The error I get is that the field is not NULL capable.
Data mapping error on member EMPDETS.
Message . . . . : Data mapping error on member EMPDETS.
Cause . . . . . : A data mapping error occurred on field RATED in record
number 0, record format EMPREC, member number 1, in member EMPDETS file
EMPDETS in library TSTMDTA, because of error code 20. The error code
20 -- A field that is not null capable could not be set to null.
This is after I changed some of the fields to be null capable. I am playing
with a Limited Availability API so I cannot pass on all of the information
which is making this even harder to resolve..

can create a nullflds map over a file of say 8,000 null fields and

could simple access the in_null_map with a ptr and set the memory
directly with 0xF0 or 0xF1?
I don't think you really need anything special for the null field map; an
ordinary char* should do fine.
But in an earlier post, it looked like you were doing just that. At least,
I'm assuming that nvi_set was defined as a char *:
for(j = 0; j < NVI_Buf->Length_NVI; j++,data++,nvi_set++) {
if(*data == 0xF9)
*nvi_set = __NULL_VALUE;
else
*nvi_set = __NOT_NULL_VALUE;
}
The only think I can think of here is that NVI_Buf->Length_NVI is greater
fp->null_map_len. If so, you'd be corrupting some other storage which might
lead to the errors you're seeing. I don't think you've told us exactly what
errors you're seeing.
