e.g. -EFAULT if you pass an invalid pointer. This behaviour is documented in the syscalls(2) man page.-1 to -4095 means error, anything else means success. The return value is called exit status. This value can be used to determine whether a command completed successfully or unsuccessfully. If the command exits successfully, the exit status will be zero, otherwise it will be a nonzero value. The following script reports the success/failure status of a command: When a bash function ends its return value is its status: zero for success, non-zero for failure.

Early versions of System V Unix stored the wtmp file in the /etc directory.

An exit code, or sometimes known as a return code, is the code returned to a parent process by  The return value of system() is one of the following: * If command is NULL, then a nonzero value if a shell is available, or 0 if no shell is available. * If a child  fork() returns a positive value, the process ID of the child process, to the parent.

The return value of the command is in the upper 8 bits of the return value. So you bitwise shift the return value by 8. When the python process completes successfully, value returned by system () is 0. When the python process is killed mid-execution (using kill -9 pid ), value returned by system () is 9. When the python process fails on its own due to incorrect parameters, value returned by system () is 512.

* If a child process could not be created, or its status could not be retrieved, the return value is -1 and errno is set to indicate the error. The meanings of return values for each sys call are documented in the section 2 man pages, like read(2). (sys_read is the raw system call that the glibc read() function is a very thin wrapper for.) Most man pages have a whole section for the return value. e.g.

Linux system call return values (in EAX/RAX on x86) are either "normal" success, or a -errno code for error. e.g. -EFAULT if you pass an invalid pointer. This behaviour is documented in the syscalls(2) man page.-1 to -4095 means error, anything else means success. The return value is called exit status. This value can be used to determine whether a command completed successfully or unsuccessfully. If the command exits successfully, the exit status will be zero, otherwise it will be a nonzero value.
