NLIST(3)                  OpenBSD Programmer's Manual                 NLIST(3)

NAME
     nlist - retrieve symbol table name list from an executable file



SYNOPSIS
     #include <nlist.h>

     int
     nlist(const char *filename, struct nlist *nl);

DESCRIPTION
     The nlist() function retrieves name list entries from the symbol table of
     an executable file. (See a.out(5).)  The argument nl is set to reference
     the beginning of the list.  The list is preened of binary and invalid da-
     ta; if an entry in the name list is valid, the n_type and n_value for the
     entry are copied into the list referenced by nl. No other data is copied.
     The last entry in the list always has its n_name field set to NULL.

RETURN VALUES
     The number of invalid entries is returned if successful; otherwise, if
     the file filename does not exist or is not an executable, the returned
     value is -1.
