# NAME

`kvm_nlist` —
retrieve symbol table names from a kernel image

# LIBRARY

Kernel Data Access Library (libkvm, -lkvm)

# SYNOPSIS

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

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

# DESCRIPTION

`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.

If kd was created by a call to `kvm_open`() with a `NULL` executable image name, `kvm_nlist`() will use /dev/ksyms to retrieve the kernel symbol table.

# RETURN VALUES

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

# FILES

/dev/ksyms
