Exit Status 112 Qshell Interpreter (qsh) v 0 on success v >0 if an error occurs [ Legal | AS/400 Glossary ]
Chapter 5. Qshell APIs The following APIs (application program interfaces) are available for Qshell: v QzshSystem() - Run a QSH Command v QzshCheckShellCommand() - Find QSH Command [ Legal | AS/400 Glossary ] QzshSystem() - Run a QSH Command Parameters Authorities Return Value Syntax #include int QzshSystem( const char *command ); Threadsafe: Yes The QzshSystem() function runs the specified shell command by spawning a child process and invoking qsh in the child process. qsh interprets and runs command and then exits. The QzshSystem() function returns when the child process has ended. While the QzshSystem() function is waiting for the child process to end, it ignores the SIGQUIT and SIGINT signals, and blocks the SIGCHLD signal. The QzshSystem() function does not affect the status information of any other child processes started by the calling process. *command (Input) Pointer to null-terminated string that contains the shell command to run. Object Referred To Authority Required errno Each directory in the path name preceding the executable file *X EACCES Executable file *X EACCES If executable file is a shell script *RX EACCES value QzshSystem() was successful. The return value is the status returned from the waitpid() function. An application can use the macros provided in the sys/wait.h header file to interpret the status information from the child process. The return value can be a negative number. -1 Qp0zSystem() was not successful. The errno value is set to indicate the error. © Copyright IBM Corp. 1998, 1999 113
