#include opcapi.h
char *opcdata_get_str(
const opcdata
data, /* in */
int attribute /* in */
);
Parameters
data
attribute
Description
Instead of a status value, the function
opcdata_get_str()
returns a pointer to the desired
string value. This function can, therefore, be used directly in
another function call.
Return Values
Returns a character pointer to the value of the defined attribute in the data area. The pointer points into the internal data area. Modification of the attribute is only allowed using opcdata_set_str(); direct access to the string is not supported.
Versions
HPOM for Windows A.07.50 and later
