NLIST(3)               FreeBSD Library Functions Manual               NLIST(3)

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

LIBRARY
     Standard C Library (libc, -lc)

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
     data; 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 is always NULL.

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