NAME [Toc] [Back]
cr_info - retrieve crash dump information
SYNOPSIS [Toc] [Back]
cr_info_t *cr_info(CRASH *crash_cb);
DESCRIPTION [Toc] [Back]
The cr_info() function returns a pointer to a cr_info_t structure with
information about an open crash dump.
The cr_info_t structure contains the following fields. Note that
there is no necessary correlation between the placement in this list
and the order in the structure, and the structure may contain other,
reserved fields. In the future, this structure may change in size and
should not be copied to avoid compatibility problems with various
char *cri_hostname Name of system dumped
char *cri_model Model string from system
char *cri_panic Panic message
char *cri_release Release string from system
char *cri_dumptime Time of the crash dump
char *cri_savetime Time crash dump saved
uint64_t cri_chunksize Size of uncompressed image files.
uint64_t cri_memsize Physical size of memory (bytes)
uint64_t cri_num_err Number of error messages
char **cri_errmsg Error messages from INDEX file
uint64_t cri_num_warn Number of warning messages
char **cri_warnmsg Warning messages from INDEX file
uint64_t cri_num_mod Number of module structures
cri_modinfo_t *cri_modinfo Array of module structures
uint32_t cri_num_nodes Number of nodes
uint32_t cri_monarch_node Physical monarch node number
The fields cri_hostname, cri_model, cri_panic, cri_release,
cri_dumptime, and cri_savetime are all null-terminated strings;
respectively, representing the name and model of the system that
dumped, the panic message, the release version string of the kernel,
and the times that the system dumped and the dump was saved. The
amount, in bytes, of physical memory on the system is in cri_memsize.
The target size, in bytes, of individual uncompressed image files is
in cri_chunksize. cri_errmsg and cri_warnmsg are arrays of nullterminated
strings with the list of saved messages. cri_num_err and
cri_num_warn are the number of strings in each list. cri_modinfo is
an array of cri_modinfo_t structures defining the loaded kernel
modules; there are cri_num_mod elements in the array. cri_num_nodes
is the number of nodes contained on the machine and cri_monarch_node
is the physical node number of the monarch.

The cri_modinfo_t structure contains information specific to kernel
modules loaded into memory at the time of the system crash. The
specific fields are:
char *mdi_loadpath File path when loaded into memory
char *mdi_savepath File path when saved in crash directory
uint64_t mdi_size Size in bytes
uint64_t mdi_checksum Checksum of the file from cksum(1)
Again, the order of these fields within the structure is not
specified, and other reserved fields may be present in the structure.
The caller must not modify any information in any of the structures
returned by cr_info().
RETURN VALUE [Toc] [Back]
cr_info() returns a pointer to the cr_info_t structure described
above. If crash_cb is not a valid descriptor of a crash dump opened
with cr_open(), the return value is undefined.
EXAMPLES [Toc] [Back]
Assuming a process opened a crash dump, the following call to
cr_info(3) retrieves the information about the open crash dump.
cri = cr_info(crshdes);
