.SH DESCRIPTION
|
|
.LP
|
|
The \fIkillpg\fP() function shall send the signal specified by \fIsig\fP
|
|
to the process group specified by \fIpgrp\fP.
|
|
.LP
|
|
If \fIpgrp\fP is greater than 1, \fIkillpg\fP(\fIpgrp\fP,\ \fIsig\fP)
|
|
shall be equivalent to
|
|
\fIkill\fP(-\fIpgrp\fP,\ \fIsig\fP). If \fIpgrp\fP is less than or
|
|
equal to 1, the behavior of \fIkillpg\fP() is
|
|
undefined.
