No predicates are currently defined. 59.Pp 60The number of files found is returned in the reference parameter 61.Fa cnt . 62The files are returned as a contiguous array of kinfo_file structures. 63This memory is owned by kvm and is not guaranteed to be persistent across 64subsequent kvm library calls. Data should be copied out if it needs to be 65saved. 66.Sh RETURN VALUES 67.Fn kvm_getfiles 68will return NULL on failure. 69.Sh SEE ALSO 70.Xr kvm 3 , 71.Xr kvm_close 3 , 72.Xr kvm_geterr 3 , 73.Xr kvm_nlist 3 , 74.Xr kvm_open 3 , 75.Xr kvm_openfiles 3 , 76.Xr kvm_read 3 , 77.Xr kvm_write 3 78.Sh BUGS 79This routine does not belong in the kvm interface. 80
