INFORMIX-ESQL/C Programmer's Manual ESQL/C Function Library

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

void *ifx_var_getdata(var_bin)

	var binary **var_bin;

void *ifx_var_getdata(lvar)

	lvarchar **lvar;

 



var_bin  

is the address of the var binary host variable whose data is retrieved. 


lvar

is the address of the lvarchar pointer host variable whose data is retrieved.

The ifx_var_getdata() function returns the data as a void * pointer. Your ESQL/C 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 *).
