The return value is the zero +in the child and the process-id number of the child in the parent, +or \-1 upon error. In the latter case, +.B ERRNO +indicates the problem. +In the child, \fBPROCINFO["pid"]\fP and \fBPROCINFO["ppid"]\fP +are updated to reflect the correct values. +.TP +.B waitpid() +This function takes a numeric argument, which is the process-id to +wait for. The return value is that of the +.IR waitpid (2) +system call. +.TP +.B wait() +This function waits for the first child to die. +The return value is that of the +.IR wait (2) +system call. +.\" .SH NOTES +.SH BUGS +There is no corresponding +.B exec() +function. +.PP +The interfaces could be enhanced to provide more facilities, +including pulling out the various bits of the return status. +.SH EXAMPLE +.ft CW +.nf +@load "fork" +\&... +if ((pid = fork()) == 0) + print "hello from the child" +else + print "hello from the parent" +.fi +.ft R +.SH "SEE ALSO" +.IR "GAWK: Effective AWK Programming" , +.IR filefuncs (3am), +.IR fnmatch (3am), +.IR inplace (3am), +.IR ordchr (3am), +.IR readdir (3am), +.IR readfile (3am), +.IR revoutput (3am), +.IR rwarray (3am), +.IR time (3am). +.PP +.IR fork (2), +.IR wait (2), +.IR waitpid (2). +.SH AUTHOR +Arnold Robbins, +.BR arnold@skeeve.com . +.SH COPYING PERMISSIONS +Copyright \(co 2012, 2013, +Free Software Foundation, Inc. +.PP +Permission is granted to make and distribute verbatim copies of +this manual page provided the copyright notice and this permission +notice are preserved on all copies. +.ig +Permission is granted to process this file through troff and print the +results, provided the printed document carries copying permission +notice identical to this one except for the removal of this paragraph +(this paragraph not being relevant to the printed manual page). +.. +.PP +Permission is granted to copy and distribute modified versions of this +manual page under the conditions for verbatim copying, provided that +the entire resulting derived work is distributed under the terms of a +permission notice identical to this one. +.PP +Permission is granted to copy and distribute translations of this +manual page into another language, under the above conditions for +modified versions, except that this permission notice may be stated in +a translation approved by the Foundation. +.\" vim: set filetype=nroff : -- cgit v1.2.3
