nlist(3X)               LIBRARY FUNCTIONS               nlist(3X)



NAME
     nlist - get entries from name list

SYNOPSIS
     #include <nlist.h>

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

     cc ... -lmld

DESCRIPTION
     NOTE: The nlist subroutine has moved  from  the  standard  C
     library  to the ``mld'' library due to the difference in the
     object file format.  Programs that need to use nlist must be
     linked with the -lmld option.

     Nlist examines the name list in the given executable  output
     file  and  selectively  extracts a list of values.  The name
     list consists of an array of  structures  containing  names,
     types  and values.  The list is terminated with a null name.
     Each 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.  For the structure declaration, see
     /usr/include/nlist.h.

     This subroutine is useful for examining the system name list
     kept  in  the  file  /unix.  In this way programs can obtain
     system addresses that are up to date.

     a.out(5)

DIAGNOSTICS
     If the file cannot be found or if it is not a valid namelist
     -1  is  returned;  otherwise, the number of unfound namelist
     entries is returned.

     The type entry is set to 0 if the symbol is not found.
