Process Control error constants

Costanti	Descrizione
`PCNTL_E2BIG` (int)	Argument list too long
`PCNTL_EACCES` (int)	Permission denied
`PCNTL_EAGAIN` (int)	Resource temporarily unavailable
`PCNTL_ECAPMODE` (int)	The process attempted an operation not permitted in capability mode while running in capability mode.
`PCNTL_ECHILD` (int)	No child processes
`PCNTL_EFAULT` (int)	Bad address
`PCNTL_EINTR` (int)	Interrupted function call
`PCNTL_EINVAL` (int)	Invalid argument
`PCNTL_EIO` (int)	Input/output error
`PCNTL_EISDIR` (int)	Is a directory
`PCNTL_ELIBBAD` (int)	Accessing a corrupted shared library.
`PCNTL_ELOOP` (int)	Too many levels of symbolic links
`PCNTL_EMFILE` (int)	Too many open files. Commonly caused by exceeding the `RLIMIT_NOFILE` resource limit. Can also be caused by exceeding the limit specified in `/proc/sys/fs/nr_open`.
`PCNTL_ENAMETOOLONG` (int)	Filename too long
`PCNTL_ENFILE` (int)	Too many open files in system. On Linux, this is probably a result of encountering the `/proc/sys/fs/file-max` limit.
`PCNTL_ENOENT` (int)	No such file or directory. Typically, this error results when a specified pathname does not exist, or one of the components in the directory prefix of a pathname does not exist, or the specified pathname is a dangling symbolic link.
`PCNTL_ENOEXEC` (int)	Exec format error
`PCNTL_ENOMEM` (int)	Not enough space/cannot allocate memory
`PCNTL_ENOSPC` (int)	No space left on device
`PCNTL_ENOTDIR` (int)	Not a directory
`PCNTL_EPERM` (int)	Operation not permitted
`PCNTL_ESRCH` (int)	No such process
`PCNTL_ETXTBSY` (int)	Text file busy
`PCNTL_EUSERS` (int)	Too many users

RFTSIGZMB (int)

P_ALL (int): Select any children.
P_PID (int): Select by process ID.
P_PGID (int): Select by process group ID.
P_PIDFD (int): Select by PID file descriptor. Specific to Linux (since Linux 5.4).
P_UID (int): Select by effective user ID. Specific to NetBSD and FreeBSD.
P_GID (int): Select by effective group ID. Specific to NetBSD and FreeBSD.
