NAME

cr_isaddr - validate whether physical page number was dumped

SYNOPSIS

#include <libcrash.h>

int cr_isaddr(CRASH *crash_cb, uint64_t pagenum, int *avail);

DESCRIPTION

The cr_isaddr() checks to see if the speciﬁed page number, pagenum , is present in the open crash

dump represented by crash_cb . It sets the Boolean to which avail points to indicate the presence (1) or

absence (0) of the page.

RETURN VALUE

Returns zero for success. Other possible return values are described in libcrash (5).

EXAMPLES

Assuming a process opened a crash dump, the following call to cr_isaddr (3) tests for the availability of

page 256:

#include <libcrash.h>

CRASH cr_cb;

int avail;

int retval = cr_isaddr(&cr_cb, (uint64_t)256, &avail);

if (retval >= 0 && avail > 0) {

/* Read and process page 256 */

} /* Else ignore pages that are not available */
