Planning the Port To ensure proper planning of an X client port, be sure to carefully examine the HP Motif/iX implementation differences described in chapter 2. In addition, you must acquire a good understanding of the differences between the C compilers on HP-UX and MPE/iX [REV BEG] and the differences between the c89 interface to the C/iX compiler and the HP-UX cc interface.[REV END] You should experience little difficulty if your HP-UX C source code is written to ANSI C because both HP-UX and MPE/iX versions of the C compiler provide for full ANSI C conformance. If however, you have chosen to use non-ANSI extensions to C in your source code, you must examine whether or not the C/iX compiler provides the same functionality as the HP-UX version of C and make modifications where necessary. [REV BEG] In addition, if your application conforms to the POSIX.1 standard, you should have little difficulty porting your application. However, you should examine all external routines in your source code to determine if they are part of the POSIX.1 standard. For more information on the POSIX.1 standard, see MPE/iX Developer's Kit Reference Manual, Vol. 1 (36430-90001).[REV END]
