fork
FORK(3F) FORK(3F) NAME
fork - create a copy of this process SYNOPSIS
integer function fork() DESCRIPTION
Fork creates a copy of the calling process. The only distinction between the 2 processes is that the value returned to one of them (referred to as the `parent' process) will be the process id of the copy. The copy is usually referred to as the `child' process. The value returned to the `child' process will be zero. All logical units open for writing are flushed before the fork to avoid duplication of the contents of I/O buffers in the external file(s). If the returned value is negative, it indicates an error and will be the negation of the system error code. See perror(3F). A corresponding exec routine has not been provided because there is no satisfactory way to retain open logical units across the exec. How- ever, the usual function of fork/exec can be performed using system(3F). FILES
