NAME
cr_info - retrieve crash dump information
SYNOPSIS
#include <libcrash.h>
cr_info_t *cr_info(CRASH *crash_cb);
DESCRIPTION
The cr_info() function returns a pointer to a
cr_info_t structure with information about an open
crash dump.
cr_info_t
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 compa-
tibility problems with various releases.
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 null-terminated 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.
cri_modinfo_t
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
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
Assuming a process opened a crash dump, the following call to cr_info (3) retrieves the information about
the open crash dump.
