The ifx_var_getdata() function

The ifx_var_getdata() function returns the data from an lvarchar or var binary host variable.

Syntax

var binary 
void *ifx_var_getdata(var_bin)
   var binary **var_bin;

void *ifx_var_getdata(lvar)
   lvarchar **lvar;
var_bin
The address of the var binary host variable whose data is retrieved.

Usage

The ifx_var_getdata() function returns the data as a void * pointer. Your application must cast this pointer to the correct data type. When you use ifx_var_getdata() on an lvarchar pointer, you must cast the returned (void) pointer to a C-language character pointer (char *).
