syms(5) [ultrix man page]

syms(5) 							File Formats Manual							   syms(5)

Name
       syms - MIPS symbol table

Syntax
       #include < sym.h>
       #include < symconst.h>

Description
       Unlike the COFF symbol table, the MIPS symbol table consists of many tables unbundling information.  The symbol table should be viewed as a
       network-style database designed for space and access efficiency.

       The following structures or tables appear in the MIPS symbol table:

       TABLE			CONTENTS

       Symbolic header		Sizes and locations of all other tables

       File descriptors 	Per file locations for other tables

       Procedure descriptors
				Frame information and location of procedure info

       Local symbols		Local type, local variable, and scoping info

       Local strings		String space for local symbols

       Line numbers		Compacted by encoding, contains a line per instruction

       Relative file descriptors
				Indirection for interfile symbol access

       Optimization symbols
				To be defined

       Auxiliary symbols	Variable data type information for each local symbol

       External symbols 	Loader symbols (global text and data)

       External strings 	String space for external symbols

       Dense numbers		Index pairs (file, symbol) for compiler use

       External and local symbols contain the standard concept of a symbol as follows:
       struct
       {
	    long iss; /* index into string space */
	    long value;    /* address, size, etc., depends on sc and st */
	    unsigned  st: 6;	/* symbol type (e.g. local, param, etc.) */
	    unsigned  sc: 5;	/* storage class (e.g. text, bss, etc.) */
	    unsigned  reserved: 1;
	    unsigned  index;	/* index to symbol or auxiliary tables */
       };

ldtbread(3x)															      ldtbread(3x)

Name
       ldtbread - read an indexed symbol table entry of a common object file

Syntax
       #include <stdio.h>
       #include <filehdr.h>
       #include <syms.h>
       #include <ldfcn.h>

       int ldtbread (ldptr, symindex, symbol)
       LDFILE *ldptr;
       long symindex;
       pSYMR *symbol;

Description
       The  reads  the	symbol table entry specified by symindex of the common object file currently associated with ldptr into the area of memory
       beginning at symbol.

       returns success or failure.  If symindex is greater than the number of symbols in the object file or if it cannot read the specified symbol
       table entry, fails.

       The  local  and	external  symbols  are concatenated into a linear list.  Symbols are accessible from symnum zero to SYMHEADER(ldptr).isym-
       Max+SYMHEADER(ldptr).iextMax.  The index and iss fields of the SYMR are made absolute (rather than file relative) so that routines and pro-
       ceed normally given those indices.  Only the sym part of externals is returned.

       Note that the first symbol in the symbol table has an index of zero.
