int Ns_ConfigGetInt(
char *sectionName,
char *key,
int *valuePtr
);
This function converts the specified value into an int and stores it in valuePtr. If the key does not exist in the config file or it is not an integer, the function returns NS_FALSE. Otherwise it returns NS_TRUE.
int n;
if (Ns_ConfigGetInt("MySect", "MyKey", &n) != NS_TRUE) {
/* Integer was not present or invalid - set a default. */
n = 5; /* off */
}
