No predicates are currently defined. +.Pp +The number of files found is returned in the reference parameter +.Fa 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. +.Sh RETURN VALUES +.Fn kvm_getfiles +will return NULL on failure. +.Sh BUGS +This routine does not belong in the kvm interface. +.Sh SEE ALSO +.Xr kvm 3 , +.Xr kvm_close 3 , +.Xr kvm_geterr 3 , +.Xr kvm_nlist 3 , +.Xr kvm_open 3 , +.Xr kvm_openfiles 3 , +.Xr kvm_read 3 , +.Xr kvm_write 3 |
