crashconf(2) -- configure system crash dumps
|
|
crashconf() changes the current system crash dump configuration. The crash dump configuration consists of: + The crash dump device list. This list identifies all devices that can be used to store a crash dump. The devices are used in reverse order, last specified to first. + The included class list. This list identifies all system memory classes that must be included in any crash dump. + The exclu... |

creat(2) -- create a new file or rewrite an existing one
|
|
The creat() system call creates a new regular file or prepares to rewrite an existing file named by the path name pointed to by path. If the file exists, its length is truncated to 0, and its mode and owner are unchanged. Otherwise, the file's owner ID is set to the effective user ID of the process. If the set-group-ID bit of the parent directory is set, the file's group ID is set to the group I... |

creat64(2) -- non-POSIX standard API interfaces to support large files
|
|
New API's to support large files in 32-bit applications. These API interfaces are not a part of the POSIX standard and may be removed in the future. creat64() The creat64() function returns a file descriptor which can be used to grow the file past 2 GB if desired. All other functional behaviors, returns, and errors are identical to creat(). fstat64() The fstat64() function is identical to fstat()... |

dup(2) -- duplicate an open file descriptor
|
|
fildes is a file descriptor obtained from a creat(), open(), dup(), fcntl(), or pipe() system call. dup() returns a new file descriptor having the following in common with the original: + Same open file (or pipe). + Same file pointer (i.e., both file descriptors share one file pointer). + Same access mode (read, write or read/write). + Same file status flags (see fcntl(2), F_DUPFD). The new file d... |

dup2(2) -- duplicate an open file descriptor to a specific slot
|
|
fildes is a file descriptor obtained from a creat(), open(), dup(), fcntl(), or pipe() system call. fildes2 is a non-negative integer less than the maximum value allowed for file descriptors. dup2() causes fildes2 to refer to the same file as fildes. If fildes2 refers to an already open file, the open file is closed first. The file descriptor returned by dup2() has the following in common with fil... |

errno(2) -- error indicator for function calls
|
|
Many functions in the HP-UX operating system indicate an error condition by returning an otherwise out-of-range value (usually -1). Most of these functions set the symbol errno, that is defined in errno.h, to a nonzero code value that more specifically identifies the particular error condition that was encountered. In most cases, the manpages for functions that set errno list those errno values an... |

exec(2) -- execute a file
|
|
The exec*() system calls, in all their forms, load a program from an ordinary, executable file into the current process, replacing the current program. The path or file argument refers to either an executable object file or a file of data for an interpreter. In the latter case, the file of data is also called a script file.

exit(2) -- terminate process
|
|
exit() terminates the calling process and passes status to the system for inspection, see wait(2). Returning from main in a C program has the same effect as exit(); the status value is the function value returned by main (this value is undefined if main does not take care to return a value or to call exit() explicitly). If the calling process is multithreaded, all threads/lightweight process in th... |

fchdir(2) -- change working directory
|
|
chdir() and fchdir() cause a directory pointed to by path or fildes to become the current working directory, the starting point for path searches of path names not beginning with /. path points to the path name of a directory. fildes is an open file descriptor of a directory. For a directory to become the current working directory, a process must have execute (search) access to the directory. |
