WHDLoad's dumps and logfiles

Mainly for debugging purposes WHDLoad can create various dump and logfiles.

Memory dump

 A memory dump is the whole memory used by the installed program written to a file. The size of the dump depends on the installed program (it is equal to the value of ws_BaseMemSize from the Slave structure). A memory dump will be created if the DebugKey is pressed or after an error the CoreDump gadget will be activated. The name of the memory dump file created is ".whdl_memory". The default location is "PROGDIR:" but can be changed with the CoreDumpPath option. An existing file with the same name will always be overwritten. If the installed program uses additional Fast-Memory, it is saved under the filename ".whdl_expmem".

Register dump

 The register dump contains the complete status of the CPU (including MMU), the Cia and the Custom chips. Some Cia and Custom registers are not readable, these are only contained in the dump file if Snoop mode was active. The information will be written to an ASCII file with some highlighting done using Escape sequences (using CSI - ControlSequenceIntroducer, decimal 155). To view, a program which supports Escape sequences is recommended (e.g. More, MuchMore, Multiview, ...). The name of the dump file is ".whdl_register", the default location is "PROGDIR:" but can be changed with the CoreDumpPath option. If a file with the same name already exists, the dump will be appended - otherwise a new file will be created.

File access log

 All disk accesses will be logged if the FileLog option has been activated. This feature will be very useful to analyze the disk operations of the installed program for debugging and optimizing purposes. Because the FileLog option disables caching of files and disk images it is also useful to simulate and check the operation similar to a low memory situation where WHDLoad can't cache anything. The following resload function will create an entry in the log file: Each file access via the functions above creates one line in the log file, the line identifies the called function and all the parameters. The information will be written to an ASCII file, the name of the dump file is ".whdl_filelog", the default location is "PROGDIR:" but can be changed with the CoreDumpPath option.
