The kvm_nlist() function retrieves the symbol table entries indicated by the name list argument amp;nl. This argument points to an array of nlist structures, terminated by an entry whose n_name field is NULL (see nlist(3)). Each symbol is looked up using the n_name field, and if found, the corresponding n_type and n_value fields are filled in. These fields are set to 0 if the symbol is not found.

The kldsym(2) system call is used to locate symbols in live kernels. This is a less than perfect emulation of the nlist values but has the advantage of being aware of kernel modules and is reasonably fast.

The kvm_nlist2() function retrieves the symbol table entries indicated by the name list argument nl. This argument points to an array of struct kvm_nlist structures, terminated by an entry whose n_name field is NULL These structures are similar to the nlist structures used by kvm_nlist() except that the n_value field uses a different type (kvaddr_t) to avoid truncation when examining non-native kernel images.
