45 .Nd retrieve symbol table names from a kernel image
52 .Fn kvm_nlist "kvm_t *kd" "struct nlist *nl"
55 retrieves the symbol table entries indicated by the name list argument
57 This argument points to an array of nlist structures, terminated by
58 an entry whose n_name field is
62 Each symbol is looked up using the n_name field, and if found, the
63 corresponding n_type and n_value fields are filled in. These fields are set
64 to 0 if the symbol is not found.
67 is used to locate the symbol. This is a less than perfect emulation
68 of the nlist values but has the advantage of being aware of kernel modules
69 and is reasonably fast.
73 function returns the number of invalid entries found.
74 If the kernel symbol table was unreadable, -1 is returned.
