kvm_close
KVM_OPEN(3) BSD Library Functions Manual KVM_OPEN(3)NAME
kvm_open, kvm_openfiles, kvm_close -- initialize kernel virtual memory access
LIBRARY
Kernel Data Access Library (libkvm, -lkvm)
SYNOPSIS
#include <fcntl.h>
#include <kvm.h>
kvm_t *
kvm_open(const char *execfile, const char *corefile, const char *swapfile, int flags, const char *errstr);
kvm_t *
kvm_openfiles(const char *execfile, const char *corefile, const char *swapfile, int flags, char *errbuf);
int
kvm_close(kvm_t *kd);
DESCRIPTION
The functions kvm_open() and kvm_openfiles() return a descriptor used to access kernel virtual memory via the kvm(3) library routines. Both
active kernels and crash dumps are accessible through this interface.
The execfile argument is the executable image of the kernel being examined. This file must contain a symbol table. If this argument is
NULL, the currently running system is assumed, as determined from getbootfile(3).
The corefile argument is the kernel memory device file. It can be either /dev/mem or a crash dump core generated by savecore(8). If
corefile is NULL, the default indicated by _PATH_MEM from <paths.h> is used. It can also be set to a special value /dev/null by utilities
like ps(1) that do not directly access kernel memory.
The swapfile argument is currently unused.
The flags argument indicates read/write access as in open(2) and applies only to the core file. Only O_RDONLY, O_WRONLY, and O_RDWR are per-
mitted.
There are two open routines which differ only with respect to the error mechanism. One provides backward compatibility with the SunOS kvm
library, while the other provides an improved error reporting framework.
The kvm_open() function is the Sun kvm compatible open call. Here, the errstr argument indicates how errors should be handled. If it is
NULL, no errors are reported and the application cannot know the specific nature of the failed kvm call. If it is not NULL, errors are
printed to stderr with errstr prepended to the message, as in perror(3). Normally, the name of the program is used here. The string is
assumed to persist at least until the corresponding kvm_close() call.
The kvm_openfiles() function provides BSD style error reporting. Here, error messages are not printed out by the library. Instead, the
application obtains the error message corresponding to the most recent kvm library call using kvm_geterr() (see kvm_geterr(3)). The results
are undefined if the most recent kvm call did not produce an error. Since kvm_geterr() requires a kvm descriptor, but the open routines
return NULL on failure, kvm_geterr() cannot be used to get the error message if open fails. Thus, kvm_openfiles() will place any error mes-
sage in the errbuf argument. This buffer should be _POSIX2_LINE_MAX characters large (from <limits.h>).
RETURN VALUES
The kvm_open() and kvm_openfiles() functions both return a descriptor to be used in all subsequent kvm library calls. The library is fully
re-entrant. On failure, NULL is returned, in which case kvm_openfiles() writes the error message into errbuf.
The kvm_close() function returns 0 on success and -1 on failure.

There should not be two open calls. The ill-defined error semantics of the Sun library and the desire to have a backward-compatible library
for BSD left little choice.
