Structure variable in C routine

[s_porkalai]

Hi,
In the attached C Routine, how to pass the values from DS to a C structure which has 2 variables (length, bytes[66000]).

Code: Select all

#define SQL_TEXT Latin_Text
#include "/ds/data/sqltypes_td.h"
#include <string.h>
#include <stdlib.h>
struct VARBYTE_D
{
   long length;
   BYTE bytes[66000];
};
void vbtovc(struct VARBYTE_D *inputvarbytes, BYTE *result, char sqlstate[6])
{
strcpy(sqlstate, "0000");
for(long idx=inputvarbytes->length-1;idx>=0;idx--)
{
   BYTE b= *((BYTE *)(inputvarbytes->bytes)+ idx);
    *(result+idx) = b?b:' ';
}
 *(result + inputvarbytes->length) = 0x00;
return
}

Thanks in advance

There is no mechanism for passing structures. I invite you to consider, however, that every structure is a string of characters (or, perhaps, a Raw data type in Orchestrate terminology) so, if you were to pass one of these, and set up your structure as a pointer to the same address, then you ought to be able to achieve what you desire.

But, indeed, what you are doing could as readily be done with ordinary character strings, could it not?
