Parameters of BusinessDataQuery


I have a query where I show a list of records and I'm using an API "BusinessDataQuery" on a form I have a variable like "http://../API/bdm/businessData/businessDataType?q=queryName&p=0&c=10&f=param=value". My question is for parameter 'c', if I want to show all records, does exist something to avoid this parameter ? I could put a big number I suppose but in real world I don't know what it can arrive. I know that I must use an 'f' to filter obviously but if someone knows a little more of details about the syntax or an exemple I appreciate it. On Bonita documentation I've found but it doesn't explain the maximum value for parameter 'c'.

Thanks in advance.
