E.1. - Compiling user functions
Normally you run the shell script
$CPLOTHOME/bin/makefunc
from the function directory to compile your user functions.
That file
usually invokes the C compiler to compile your module and link it
with the appropriate overhead modules.
If your user function contains
the string
cplot_compile: followed by commands to compile your
function, those commands are used instead of the default commands
from
makefunc.
The commands can refer to the
make
utility
or invoke the C compiler directly.
Possible ways of including the
information in a function source file are:
/* * cplot_compile: make my_func.5 */or
#if 0
cplot_compile: make my_func.5
#endif
Accessing and modifying the data structure passed to and from the plot program is simplified by a set of macros that is brought into your program with the line of code,
#include <p_funct.h>This include file also includes another, p_plot.h, that describes the above-mentioned data structure. Both include files are found in the directory
$CPLOTHOME/include.
