Inter-Process-Communication-FIFOs Issues, queries, discussion or suggestions

Hi everyone,

I wanted to share an interesting resource I recently obtained: a comprehensive list of system call error
numbers and their descriptions. For those who are interested, you can find this list at `/usr/include/asm-generic/errno-base.h`. Understanding these errors is crucial for effective debugging and system programming. Here’s a brief overview of what I’ve learned and why I think it’s valuable for
our community.

What Are System Call Errors?

System calls are fundamental operations provided by the operating system kernel. They
allow user-level processes to request services such as file
manipulation, process control, and network communication. However, these
calls can fail due to various reasons, and when they do, they return
error numbers, commonly known as errno values.

Here are the list of system call errors available at `/usr/include/asm-generic/errno-base.h`:

#define EPERM             1      /* Operation not permitted */
#define ENOENT           2      /* No such file or directory */
#define ESRCH             3      /* No such process */
#define EINTR               4      /* Interrupted system call */
#define EIO                    5      /* I/O error */
#define ENXIO               6      /* No such device or address */
#define E2BIG               7      /* Argument list too long */
#define ENOEXEC        8      /* Exec format error */
#define EBADF              9      /* Bad file number */
#define ECHILD           10      /* No child processes */
#define EAGAIN           11      /* Try again */
#define ENOMEM        12      /* Out of memory */
#define EACCES         13      /* Permission denied */
#define EFAULT           14      /* Bad address */
#define ENOTBLK        15      /* Block device required */
#define EBUSY            16      /* Device or resource busy */
#define EEXIST            17      /* File exists */
#define EXDEV            18      /* Cross-device link */
#define ENODEV         19      /* No such device */
#define ENOTDIR        20      /* Not a directory */
#define EISDIR            21      /* Is a directory */
#define EINVAL            22      /* Invalid argument */
#define ENFILE            23      /* File table overflow */
#define EMFILE            24      /* Too many open files */
#define ENOTTY           25      /* Not a typewriter */
#define ETXTBSY         26      /* Text file busy */
#define EFBIG              27      /* File too large */
#define ENOSPC          28      /* No space left on device */
#define ESPIPE            29      /* Illegal seek */
#define EROFS             30      /* Read-only file system */
#define EMLINK            31      /* Too many links */
#define EPIPE              32      /* Broken pipe */
#define EDOM              33      /* Math argument out of domain of func */
#define ERANGE          34      /* Math result not representable */
