C Syntax
#include <copro.h>
unsigned DTL_TYPE (name_id, type)
int name_id;
int *type;
Parameters
name_id
The handle returned by DTL_C_DEFINE when the data item
was defined.
type
The coded value denoting the control-coprocessor data type you
specified with DTL_C_DEFINE. On return from DTL_TYPE, the type
variable will have one of the following values:
Type: ¬ Is: Type: ¬ Is:
DTL_TYP_RAW no conversion DTL_TYP_LONG long (int)
DTL_TYP_BYTE char DTL_TYP_ULONG unsigned
DTL_TYP_UBYTE unsigned char DTL_TYP_FLOAT float
DTL_TYP_WORD short DTL_TYP_DOUBLE double
DTL_TYP_UWORD unsigned short
¬ These symbolicnames are in COPRO.H.
Returns
Status Symbolic Name Meaning
0 DTL_SUCCESS Operation successful
19 DTL_E_NOINIT Definition table not initialized
20 DTL_E_BADID Definition ID out of range
32 DTL_E_NODEF No such data item defined
Description
Use DTL_TYPE to get the code that indicates the data type you specified
