int DatabaseSearchRecord (  FILE *  database,
char *  find,
int  casesensitive
) 
 

Searches the current record for any instance of a substring. If found, it returns 1 and positions the database pointer to the beginning of the record. If a substring is not found, it advances the pointer to the next record.
