SYNOPSIS

9       #include <nlist.h>

11       nlist(filename, nl)
12       char *filename;
13       struct nlist nl[];

DESCRIPTION

16       Nlist  examines  the  name list in the given executable output file and
17       selectively extracts a list of values.  The name list  consists  of  an
18       array  of  structures  containing names, types and values.  The list is
19       terminated with a null name.  Each name is looked up in the  name  list
20       of  the file.  If the name is found, the type and value of the name are
21       inserted in the next two fields.   If  the  name  is  not  found,  both
22       entries are set to 0.  See a.out(5) for the structure declaration.
23
24       This  subroutine  is  useful for examining the system name list kept in
25       the file /vmunix.  In this way programs  can  obtain  system  addresses
26       that are up to date.

DIAGNOSTICS

32       If  the  file  cannot  be  found or if it is not a valid namelist -1 is
33       returned;  otherwise,  the  number  of  unfound  namelist  entries   is
34       returned.
35
36       The type entry is set to 0 if the symbol is not found.
