NLIST(3C)                            SysV                            NLIST(3C)



NAME
     nlist - get entries from name list

SYNOPSIS
     #include <nlist.h>

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

DESCRIPTION
     nlist examines the name list in the executable file whose name is pointed
     to by filename, and selectively extracts a list of values and puts them
     in the array of nlist structures pointed to by nl.  The name list nl
     consists of an array of structures containing names of variables, types
     and values.  The list is terminated with a null name; that is, a null
     string is in the name position of the structure.  Each variable name is
     looked up in the name list of the file.  If the name is found, the type
     and value of the name are inserted in the next two fields.  If the name
     is not found, both entries are set to 0.  See a.out(4) for a discussion
     of the symbol table structure.

SEE ALSO
     a.out(4).

DIAGNOSTICS
     All value entries are set to 0 if the file cannot be read or if it does
     not contain a valid name list.

     nlist returns -1 upon error; otherwise it returns 0.

NOTES
     The <nlist.h> header file is automatically included by <a.out.h> for
     compatibility.  However, if the only information needed from <a.out.h> is
     for use of nlist, then including <a.out.h> is discouraged.  If <a.out.h>
     is included, the line "#undef n_name" may need to follow it.
