.::Gwyddion::dump(3pm) gwyddion .::Gwyddion::dump(3pm)NAME
Gwyddion::dump -- Gwyddion plug-in proxy dump dumb file format handling.
FUNCTIONS
read( filename )
Read a Gwyddion plug-in proxy dump file.
The file is returned as a hash table of dump key, value pairs.
Data fields are packed as references to hashes with following keys (not all has to be present): `xres' (x-resolution, in number of
samples), `yres' (y-resolution, in number of samples), `xreal' (real x size, in base SI units), `yreal' (real y size, in base SI
units), `unit-xy' (lateral units, base SI, like `m'), `unit-z' (value units, base SI, like `m' or `A'), `data' (the data field data
itself, an array of floats).
Fatal errors are not handled, the function simply dies. If you have anything meaningful to do after a fatal error, you have to catch
the error.
write( data, filename )
Write a Gwyddion plug-in proxy dump file.
The hash table to write is expected to follow the same conventions as those returned by read(), please see its description for more.
Fatal errors are not handled, the function simply dies. If you have anything meaningful to do after a fatal error, you have to catch
the error.

dump(9E) Driver Entry Points dump(9E)NAME
dump - dump memory to device during system failure
SYNOPSIS
#include <sys/types.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
int dump(dev_t dev, caddr_t addr, daddr_t blkno, int nblk);
INTERFACE LEVEL
Solaris specific (Solaris DDI). This entry point is required. For drivers that do not implement dump() routines, nodev(9F) should be used.
ARGUMENTS
dev Device number.
addr Address for the beginning of the area to be dumped.
blkno Block offset to dump memory.
nblk Number of blocks to dump.
DESCRIPTION
dump() is used to dump a portion of virtual address space directly to a device in the case of system failure. It can also be used for
checking the state of the kernel during a checkpoint operation. The memory area to be dumped is specified by addr (base address) and nblk
(length). It is dumped to the device specified by dev starting at offset blkno. Upon completion dump() returns the status of the transfer.
When the system is panicking, the calls of functions scheduled by timeout(9F) and ddi_trigger_softintr(9F) will never occur. Neither can
delay(9F) be relied upon, since it is implemented via timeout(). See ddi_in_panic(9F).
dump() is called at interrupt priority.
RETURN VALUES
dump() returns 0 on success, or the appropriate error number.
