kvm_nlist -- retrieve symbol table names from a kernel image
Kernel Data Access Library (libkvm, -lkvm)
kvm_nlist(kvm_t *kd, struct nlist *nl);
kvm_nlist() retrieves the symbol table entries indicated by the name list
argument nl. This argument points to an array of nlist structures, ter-
minated by an entry whose n_name field is NULL (see nlist(3)). Each sym-
bol 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.
kldsym(2) is used to locate the symbol. This is a less than perfect emu-
lation of the nlist values but has the advantage of being aware of kernel
modules and is reasonably fast.
The kvm_nlist() function returns the number of invalid entries found. If
the kernel symbol table was unreadable, -1 is returned.
