>&#13;    The purpose of this chapter is to document the API for every PLplot
    function that should be available across all PLplot language bindings.
    This common API between the various languages constitutes the
    most important part of the PLplot API that programmers need to know.
    Note that in C, these common API routines have a special 
    <SPAN
CLASS="QUOTE"
>"c_"</SPAN
> prefix name assigned to them in 
    <TT
CLASS="filename"
>plplot.h</TT
>.
  </P
><P
>&#13;    What follows is a list of all common API functions of the current 
    CVS HEAD with their arguments except for obsolete/deprecated API 
    functions which are listed in <A
HREF="api-obsolete.html"
>Chapter 24</A
>. The
    following information is provided for each function:
    <P

><P
>&#13;	  The redacted argument form of the function, currently used 
	  by the programming languages Fortran95, Python, Java and 
	  Perl, as well as any language specific variations that 
	  might occur on the general calling scheme described in 
	  the following paragraph.
	</P

>&#13;	  A list of PLplot examples that demonstrate how to use

    Additional PLplot API specialized for each language binding is

    the length of the arrays x and y) is not necessary, this
