// findcacofiles.C
// ===============
//
// Macro to find caco files for runs which don't have a dedicated caco file.
// Called by the script filesondisk
//
// Sometimes the DAQ aborts a run and starts itself a new one. In this cases
// the camera controll doesn't start a new file, as the command to
// start a new run was not sent by the central control. So the caco
// information is stored in the previous caco file, which has a different
// runnumber. To be able to merpp the information into the calibrated data
// file, the runnumber of the file containing the information has to be found.
// 
// findcacofiles.C searches in the database for runs which don't have a
// dedicated caco file, and searches for each of these runs, if one of the 10
// previous runs has a dedicated caco file. In case one is found, it is
// inserted into the database.
//
// Usage:
//   .x findcacofiles.C+
//
// Make sure, that database and password are corretly set in a resource
// file called sql.rc and the resource file is found.
//
// Returns 0 in case of failure and 1 in case of success.
