nlist(3ELF)						       ELF Library Functions						       nlist(3ELF)

NAME

       nlist - get entries from name list

SYNOPSIS

       cc [ flag... ] file ... -lelf [ library ... ]
       #include <nlist.h>

       int nlist(const 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, value, storage class, and section	number	of
       the name are inserted in the other fields. The type field may be set to 0 if the file was not compiled with the -g option to  cc(1B).

       nlist()	will  always  return  the information for an external symbol of a given name if the name exists in the file. If an external symbol
       does not exist, and there is more than one symbol with the specified name  in the file (such as static symbols defined in separate  files),
       the  values returned will be for the last occurrence of that name in the file. If the name is not found, all fields in the structure except
       n_name are set to 0.

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

RETURN VALUES

       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 0 on success, -1 on error.

NAME

       nlist - Gets 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 libmld.a library due to the difference in the object file format.
       Programs that need to use nlist must be linked with the -lmld flag.

       The nlist subroutine 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 BSD compatibility, the nlist subroutine allows symbol names to be preceded by an underscore.  If it does not find a symbol that matches
       the name as specified, nlist attempts to locate the symbol name with the leading underscore removed.

       For the structure declaration, see /usr/include/nlist.h.

       To  obtain  up-to-date  system addresses from the system name list kept in the file /vmunix, use the knlist subroutine.	Alternatively, use
       the getsysinfo function to obtain the name of the file from which the kernel was booted, prepend a slash character ("/") to this name,  and
       supply  the  prepended  name  to  the  nlist subroutine.  Do not specify /vmunix as the filename  to the nlist subroutine; nlist may return
       invalid symbol addresses.

ERRORS

       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.
