I am tasked with converting a VB probram to C.

I have came across some parts of code that seems odd to me, and since it has been more than 20 years since I have even seen Basic code I cannot remember how this works.

Here is the code:

[code]
Function CheckLeak(PresLeak As Boolean) As Boolean
Dim presrange As DruckType
Dim FixtureLeak As FixtureType
Dim HighPressure As Boolean
Dim First, Second, DeltaPressure As Double

....

CheckLeak = Not PresLeak
If CheckLeak Then

[\code]

This last part is where I am a bit confussed.

This is a function, but it is getting assigned something?

Then the function is called and the return result is evaluated, this part I get.

I have seen this assignment in many parts of this code, and in order to convert the code I need to understand what this is doing.

Thanks in advance.
