📚 Core Developer Handbooks & Standards
📘 POSIX Standard — The Source of Truth
Official Free Online (The Open Group):https://pubs.opengroup.org/onlinepubs/9699919799/✅ Searchable, bookmarkable, cross-referenced. Covers fork(), pthread_*, select(), etc.
IEEE Official Purchase (For Researchers):https://standards.ieee.org/standard/1003_1-2017.html
🧭 Linux man pages — Instant Command & Function Lookup
Online (Maintained by Michael Kerrisk):https://man7.org/linux/man-pages/✅ Better than terminal man command. Perfect for sharing links.
🖋️ C Language Coding Standard (CMU / Industry Best Practice)
Official Guide:https://users.ece.cmu.edu/~eno/coding/CCodingStandard.html
Key Highlights:
// Include units in variable names
uint32_t timeout_msecs;
uint32_t weight_lbs;
// Enums: ALL_CAPS with underscores
enum PinStateType {
PIN_OFF,
PIN_ON
};
// Macros: Always parenthesize
#define MAX(a,b) ((a) > (b) ? (a) : (b))
// Always use braces for if/while
if (condition) {
do_something();
}
// Initialize all variables
int error = 0;
char* name = NULL;
⌨️ C++ Coding Standard (CMU / Industry Best Practice)
Official Guide:https://users.ece.cmu.edu/~eno/coding/CppCodingStandard.html
Key Highlights:
// Class attributes: prefix with ‘a’
class MyClass {
private:
int aErrorNumber;
string* apName; // pointer
};
// Method names: Verbs
void HandleError();
int CalculateResult();
// Use namespaces
namespace MyProject {
class Utility { … };
}
// Avoid Get/Set; use same name for accessor/mutator
class Person {
public:
int Age() const { return aAge; }
void Age(int age) { aAge = age; }
private:
int aAge;
};

❓ Frequently Asked Questions (FAQ)
Q: What’s the difference between POSIX and Linux man pages?A: POSIX is the international standard (what “should” happen). Linux man pages document the actual implementation on your system. Start with man pages for quick reference, consult POSIX for deep, portable understanding.
Q: Are the CMU C/C++ coding standards mandatory?A: Not mandatory, but highly recommended for team projects. They reduce bugs, improve readability, and make code reviews smoother. They’re battle-tested in industry.
Q: Is there a free PDF of APUE?A: ❌ No, there is no legal free PDF. Please support the author by purchasing a copy. The official website offers free source code and errata, which are incredibly valuable.
Q: Which RHEL alternative should I choose: Rocky Linux or AlmaLinux?A: Both are excellent and 100% binary compatible with RHEL. Choose based on community and update philosophy. Rocky is community-driven, Alma has a foundation backing. You can’t go wrong with either.
