1.) EnumJobs
Parameters:
-pageSize=the size of the page(because of paging)
-label=the label filter, can contain wildcards *
-userName=the username filter, can contain wildcards
-status=the status of the jobs which should be returned, or 100 for all status
-createdFromTo="yyyy/MM/dd HH:mm:ss-yyyy/MM/dd HH:mm:ss"
-convertedFromTo="yyyy/MM/dd HH:mm:ss-yyyy/MM/dd HH:mm:ss"
-sortColumns="ColumName1 ASC,ColumnName DESC,..."

The createdFromTo, convertedFromTo and sortColumns can be empty strings. The available sort columns are the following:
-DateCreated
-DateConverted
-StatusCode
-UserName
-JobLabel

The function will return a structure which holds information about the search/paging:
JobEnum {
PageSize, // page size, which was requested
PagesCount, // total pages
TotalJobs, // total jobs
JobEnumID // the enum identifier
}

The JobEnumID will be used for subsequent calls of EnumJobsGetPage

2.) EnumJobsGetPage
Parameters:
- enumID: the value which is returned by the EnumJobs function
- pageIndex: the index of the page which is requested, the first page is 1
The total number of pages are also returned by the EnumJobs function
