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, 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 program kvm_mkdb(8) builds a database from a kernel's namelist. If
kd was created by a call to kvm_open() with a NULL executable image name
and the database matches the running kernel, kvm_nlist() will use the
database to speed lookups.
The kvm_nlist() function returns the number of invalid entries found. If
the kernel symbol table was unreadable, -1 is returned.
