NLIST(3)            UNIX Programmer's Manual             NLIST(3)

NAME
     nlist - get entries from name list

SYNOPSIS
     #include <a.out.h>

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

DESCRIPTION
     _N_l_i_s_t 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._o_u_t(5) for the structure
     declaration.

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

SEE ALSO
     a.out(5)

DIAGNOSTICS
     All type entries are set to 0 if the file cannot be found or
     if it does not have a valid name list.

     _N_l_i_s_t returns -1 if _f_i_l_e_n_a_m_e cannot be opened or has a bad
     magic number.  It returns 1 if _f_i_l_e_n_a_m_e has no name list.
