|section||The section in the open .ini file to check for.|
This function checks to see if a section exists in the currently
open ini. This is not a necessary check to prevent errors as, when
a section does not exist, reading from a non-existent section will
just return a defaulted value, however it can be useful to see if
an ini file has saved specific data.
global.savegame = '1';
This will set variable global.savegame to '1' if 'save1' is NOT found. With a for loop, this could be used as a basic way of working out how many save games there are for a game (ie: creating a system for multiple simultaneous save games for one game).
