NAME

nlist − nlist structure format

SYNOPSIS

#include <nlist.h>

REMARKS

The exact content of the structure defined below can be best found by examining /usr/include/nlist.h.  It varies somewhat between various HP-UX implementations. 

DESCRIPTION

nlist() can be used to extract information from the symbol table in an object file (see nlist(3C)). Since symbol tables are machine dependent (as defined in each implementation’s copy of <a.out.h>), a header file, nlist.h is defined to encapsulate the differences. 

The nlist() function, when used with the nlist structure can be used to extract certain information about selected symbols in the symbol table.  The data associated with each symbol is machine specific, thus only the name and position of the n_name field in the nlist structure is standardized by HP-UX.  The rest of the structure includes at least the value and type of the symbol.  The names and meanings of all fields not standardized will change no more than necessary. 

struct nlist {
    char    *n_name;
    /* other fields as needed;
       the following are suggested if they apply */
    long            n_value;
    unsigned char   n_type;
    unsigned char   n_length;
    short           n_unit;
    short           n_sdindex;
};
