NAME
cr_open() — open crash dump for reading
SYNOPSIS
#include <libcrash.h>
int cr_open(const char *path, CRASH **crash_cb, int flags);
DESCRIPTION
The
cr_open()
library call opens a crash dump and passes back a crash dump descriptor.
The
path
argument points to a path name naming a crash dump directory or
file, and must not exceed
PATH_MAX
bytes in length.
The
CRASH *
to which
crash_cb
points is set to a crash dump descriptor, which can then be passed to the
other
cr_*()
functions to access the crash dump.
flags
is a bitmask of zero or more of the following flag values, which affect
the operation of future calls to
libcrash
routines for this crash dump, except for
cr_verify(3),
which has its own
flags
parameter.
- CR_NOCHECKSUM
The library will not attempt to verify checksums of files in the crash
dump if this flag is set.
- CR_DELAYMSGS
The library will write messages to stderr during time-consuming operations
(decompressions and checksums) if this flag is set.
RETURN VALUE
Returns zero for success. Other possible return values are described in
libcrash(5).
EXAMPLES
The following call to
cr_open()
opens crash dump contained in the directory
/var/adm/crash/core.0
and returns the crash dump descriptor
crash_cb.
For an example of reading the crash dump
/var/adm/crash/core.0,
see the
cr_read(3)
manual entry.
#include <libcrash.h>
CRASH *crash_cb;
int ret;
ret = cr_open ("/var/adm/crash/core.0", &crash_cb, CR_DELAYMSGS);
