HP SunSoft Pascal 4.0 The C–PascalInterface, Compilation of Mixed-LanguagePrograms

The C–Pascal Interface 6

This chapter describes how to mix C and Pascal modules in the same program.

It contains the following sections:

Compilation of Mixed-Language Programs	page 89
Compatibility of Types for C and Pascal	page 90
General Parameter Passing in C and Pascal	page 93
Procedure Calls: C–Pascal	page 93
Procedure Calls: Pascal–C	page 117
Procedures and Functions as Parameters	page 132
Global Variables in C and Pascal	page 133
File-Passing Between Pascal and C	page 134

The examples in this chapter assume that you are using the ANSI C compiler.

To invoke ANSI C:

•On the Solaris 1.x environment, use the acc command

•On the Solaris 2.x environment, use the cc command

Compilation of Mixed-Language Programs

You must use the compiler option –lpcwhen you compile a C main routine that calls Pascal. –lpcincludes the Pascal object library libpc. For example:

hostname% pc -c -calign my_pascal.p hostname% cc my_pascal.o my_c.c -lpc
