NAME    [Toc]    [Back]

     kvm_nlist - retrieve symbol table names from a kernel image

LIBRARY    [Toc]    [Back]

     Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS    [Toc]    [Back]

     #include <kvm.h>
     #include <nlist.h>

     int
     kvm_nlist(kvm_t *kd, struct nlist *nl);

DESCRIPTION    [Toc]    [Back]

     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.

RETURN VALUES    [Toc]    [Back]

     The kvm_nlist() function returns the number of invalid entries found.  If
     the kernel symbol table was unreadable, -1 is returned.
