No predicates are currently defined. 58.Pp 59The number of files found is returned in the reference parameter 60.Fa cnt . 61The files are returned as a contiguous array of kinfo_file structures. 62This memory is owned by kvm and is not guaranteed to be persistent across 63subsequent kvm library calls. Data should be copied out if it needs to be 64saved. 65.Sh RETURN VALUES 66.Fn kvm_getfiles 67will return NULL on failure. 68.Sh SEE ALSO 69.Xr kvm 3 , 70.Xr kvm_close 3 , 71.Xr kvm_geterr 3 , 72.Xr kvm_nlist 3 , 73.Xr kvm_open 3 , 74.Xr kvm_openfiles 3 , 75.Xr kvm_read 3 , 76.Xr kvm_write 3 77.Sh BUGS 78This routine does not belong in the kvm interface. 79
