These are rules and recommendations This appendix contains guidelines for functions that are defined as part of the POSIX family of standards but are not included in ISO/IEC 9899-1999.

Rules

POS30-C. Use the readlink() function properly

POS31-C. Do not unlock or destroy another process's mutex

POS32-C. Include a mutex when using bit fields in a multi-threaded environment

POS32-C. Do not use vfork()

the C Standard. These rules and recommendations are not part of the core standard because they do not apply in all C language applications and because they represent an incomplete set. The intent of providing these guidelines is to demonstrate how rules and recommendations for other standards or specific implementations may be integrated with the core C recommendations.
