Hi,
A trace back will be helpful. To prevent you to made a complete debug build you can
include the
actual implementation of the sqlprc function into your cpc program and compile it with
debugging switched on.
Please rename the function sqlprc to sqlprc1 and call it before your original sqlprc
call.
regards
Burkhard
void sqlprc (long *length, int *precision, int *scale)
/* The function sqlprc exstracts precision and scale fields
from length according to the CPR_KIND_ORACLE conventions for the
NUMBER data type. All parameters are pointers to long,
length is input, precision and scale are output.
This implementation requires, that a long variable occupies
four bytes.
*/
{
long m_scale = 0xFF; /* mask for scale extraction */
long s_scale = 0x80; /* sign bit of scale field */
unsigned long m_prec = 0xFFFFFF00; /* mask for precision extraction */
long c_prec = 0x00FFFFFF; /* clear mask for shifted precision */
*scale = *length & m_scale; /* extract scale */
if (*length & s_scale) *scale = *scale | m_prec; /* propagate sign */
*precision = (*length & m_prec) >> 8 & c_prec; /* extract prec. */
return;
}
