NAME

kvm_getfiles - survey open files

LIBRARY

Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS

#include <kvm.h> #include <sys/types.h> #define _KERNEL #include <sys/file.h> #undef _KERNEL char * kvm_getfiles(kvm_t *kd, int op, int arg, int *cnt);

DESCRIPTION

kvm_getfiles() returns a (sub-)set of the open files in the kernel indi- cated by kd. The op and arg arguments constitute a predicate which lim- its the set of files returned. No predicates are currently defined. The number of files found is returned in the reference parameter cnt. The files are returned as a contiguous array of file structures, preceded by the address of the first file entry in the kernel. This memory is owned by kvm and is not guaranteed to be persistent across subsequent kvm library calls. Data should be copied out if it needs to be saved.

RETURN VALUES

kvm_getfiles() will return NULL on failure.

BUGS

This routine does not belong in the kvm interface.
