Review Comment:
val cannot be null. When adding a property with a string value if NULL, a
empty string ("") will be used instead using the celix_properties_createString
function:
```
char* celix_properties_createString(celix_properties_t* properties, const
char* str) {
if (str == NULL) {
return (char*)CELIX_PROPERTIES_EMPTY_STRVAL;
}
size_t len = strnlen(str, CELIX_UTILS_MAX_STRLEN) + 1;
size_t left = CELIX_SHORT_PROPERTIES_OPTIMIZATION_STRING_BUFFER_SIZE -
properties->currentStringBufferIndex;
char* result;
if (len < left) {
memcpy(&properties->stringBuffer[properties->currentStringBufferIndex], str,
len);
result =
&properties->stringBuffer[properties->currentStringBufferIndex];
properties->currentStringBufferIndex += (int)len;
} else {
result = celix_utils_strdup(str);
}
return result;
}
```
As result val cannot be NULL. I will update the properties iterator
documentation to make this more explicit.
