Description
       The  CHDRR  structure  (see cmplrs/stsupport.h and the represents a symbol table in memory.  A new CHDRR can be created by reading a symbol
       table in from disk. The st_readbinary and st_readst routines read a symbol table in from disk.

       The routine st_readbinary takes the file name of the symbol table and assumes the symbol table header (HDRR in sym.h occurs at  the  begin-
       ning  of  the file. The st_readst assumes that its file number references a file positioned at the beginning of the symbol table header and
       that the filebase parameter specifies where the object or symbol table file is based (for example, non-zero for archives).

       The second parameter to the read routines can be r for read only or a for appending to the symbol table. Existing local symbol, line,  pro-
       cedure,	auxiliary,  optimization,  and	local  string  tables  cannot be appended. If they didn't exist on disk, they can be created. This
       restriction stems from the allocation algorithm for those symbol table sections when read in from disk and follows the standard pattern for
       building the symbol table.

       The  symbol  table can be read incrementally.  If pchdr is zero, st_readst assumes that a symbol table has not been read yet; therefore, it
       reads in the symbol table header and file descriptors.  The flags argument is a bit mask that defines what other  tables  should  be  read.
       The  t_p*  constants  for  each table, defined in stsupport.h, can be ORed.  If flags equals -1, all tables are read.  If pchdr is set, the
       tables specified by flags are added to the tables that have already been read.  The pchdr's value can be taken from st_current_pchdr. See

       Line number entries are encoded on disk; the read routines expand them to longs.

       If the version stamp is out of date, a warning message is issued to stderr.  If the magic number in the	HDRR  is  incorrect,  st_error	is
       called. All other errors cause the read routines to read non-zero; otherwise, a zero is returned.

       The  routines st_writebinary and st_writest are symmetric to the read routines, excluding the how and pchdr parameters. The flags parameter
       is a bit mask that defines what table should be written.  The st_p* constants for each table, defined in stsupport.h, can be ORed. If flags
       equals -1, all tables are written.

       The write routines write sections of the table in the approved order, as specified in the link editor specification.

       Line numbers are compressed on disk.

       The write routines start all sections of the symbol table on four-byte boundaries.

       If the write routines encounter an error, st_error is called. After writing the symbol table, further access to the table by other routines
       is undefined.
