NLIST(3X)                                               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.  See a.out(4) for the structure
          declaration.

          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.

     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.
