Sample code

{
TYPSID gsid;
TYPCID csid;
const mfpos_t zdebut = 0, zfin = 4;
size_t bytecount;
_kernel_oserror *e;
/* gsid and csid must be given values before calling sp_fetch */
e= sp_select(gsid, csid, zdebut, zfin, &bytecount);
if(!e)	fprintf(stderr,"Expected byte count: %u\n"
	"Returned byte count: %u\n", zfin - zdebut, bytecount);
...
