No predicates are currently defined. 38.Pp 39The number of processes found is returned in the reference parameter 40.Fa cnt . 41The files are returned as a contiguous array of file structures, 42preceeded by the address of the first file entry in the kernel. 43This memory is owned by kvm and is not guaranteed to be persistent across 44subsequent kvm library calls. Data should be copied out if it needs to be 45saved. 46.Sh RETURN VALUES 47.Fn kvm_getfiles 48will return NULL on failure. 49.Pp 50.Sh BUGS 51This routine does not belong in the kvm interface. 52.Sh SEE ALSO 53.Xr kvm 3 , 54.Xr kvm_open 3 , 55.Xr kvm_openfiles 3 , 56.Xr kvm_close 3 , 57.Xr kvm_read 3 , 58.Xr kvm_write 3 , 59.Xr kvm_nlist 3 , 60.Xr kvm_geterr 3 61
