[12], For portability reasons, glibc defines the macros EXIT_SUCCESS and EXIT_FAILURE. (終了ステータスを表す 1 バイトのみを保持する) 「ゾンビ」プロセスになる。 これにより、後から wait(2) 関数を呼び出すことで、
If a command fails because of an error during expansion or redirection, the exit status is greater than zero. If status is EXIT_FAILURE, an unsuccessful termination status is returned to the host environment.
トルコ語 / Türkçe C:\Python\Python38 >> pip install -r requirements.txt >> (中略) ERROR: Command errored out with exit status 1: (中略) ERROR: Command errored out with exit status 1: 'c:\python\python38\python.exe' -u -c 'import sys Declaration. Any open file descriptors belonging to the process are closed and any children of the process are inherited by process 1, init, and the process クロアチア語 / Hrvatski Apart from zero and the macros EXIT_SUCCESS and EXIT_FAILURE, the C standard does not define the meaning of return codes. In DOS terminology, an errorlevel is an integer exit code returned by an executable program or subroutine.
For the shell’s purposes, a command which exits with a zero exit status has succeeded.
カザフ語 / Қазақша If the child terminated by exiting (as determined by the WIFEXITED() macro; the usual alternative being that it died from an uncaught signal), SUS specifies that the low-order 8 bits of the exit status can be retrieved from the status value using the WEXITSTATUS() macro.
SA_NOCLDWAIT を設定した場合、 または SIGCHLD ハンドラーを SIG_IGN に設定した場合、 The C library function void exit(int status) terminates the calling process immediately. 日本語 / 日本語 The C programming language allows programs exiting or returning from the main function to signal success or failure by returning an integer, or returning the macros EXIT_SUCCESS and EXIT_FAILURE.
Sometimes, if the codes are designed with this purpose in mind, they can be used directly as a branch index upon return to the initiating program to avoid additional tests. [15] If a process fails initialization, a Windows system error code may be returned.[16][17].

ギリシャ語 / Ελληνικά [6]. In Java, any method can call System.exit(int status), unless a security manager does not permit it.
On Unix-like systems these are equal to 0 and 1 respectively.
For example, it is common programming practice for a child process to return (exit with) zero to the parent signifying success. Severity values are divided between success (Success, Informational) and failure (Warning, Error, Fatal).[5].
The parent and the child can have an understanding about the meaning of the exit statuses. Child processes run concurrently with the parent process. Argumenty [] status kod wyjścia z programu, argument ten może posiadać wartość 0 lub EXIT_SUCCESS w przypadku pozytywnego zakończenia działania programu, w przeciwnym wypadku może zwracać EXIT_FAILURE lub dowolną wartość, z tym że liczy się ostatnie 8 najmniej znaczących bitów.
In Unix and other POSIX-compatible systems, the parent process can retrieve the exit status of a child process using the wait() family of system calls defined in wait.h. The exit status of a process in computer programming is a small number passed from a child process (or callee) to a parent process (or caller) when it has finished executing a specific procedure or delegated task. In multitasking operating systems such as Unix or Linux, new processes can be created by active processes. 中国語 (簡体字) / 简体中文
