<# .Synopsis This script determines if the current process is allowed to run. .Description This script determines if the current process is allowed to run by checking if the number of entries is less than the concurrency limit defined in the LicenseManager parameter. If it already at the at the concurrency limit, it will allow the same user on the same computer to run multiple of the same processes. .Parameter LicenseManager An object, as converted from `Watch-LMEvent`'s LicenseManager Parameter. .Parameter ProcessName The name of the Process, with the extension. .Parameter ProcesssId The Process ID of the currently running Process. .Parameter ProcesssUserName The UserName of the user running the aforementioned Process ID. #> function Assert-LMEntry { [CmdletBinding()] [OutputType([bool])] param( [Parameter(Mandatory = $true)] [array] $LicenseManager, [Parameter(Mandatory = $true)] [IO.FileInfo] $ProcessName, [Parameter(Mandatory = $true)] [int32] $ProcessId, [Parameter()] [string] $ProcessUserName ) Write-Verbose "[Assert-LMEntry] Bound Parameters: $($MyInvocation.BoundParameters | Out-String)" Write-Verbose "[Assert-LMEntry] Unbound Parameters: $($MyInvocation.UnboundParameters | Out-String)" [IO.FileInfo] $jsonFilePath = "$($LicenseManager.DirectoryPath)\${ProcessName}.json" Write-Verbose "[Assert-LMEntry] JSON File: ${jsonFilePath}" if (-not (Test-Path $jsonFilePath)) { Write-Verbose "[Assert-LMEntry] JSON file doesn't exist, so there are no entries.
