.SH DESCRIPTION
|
|
.LP
|
|
The \fI<spawn.h>\fP header shall define the \fBposix_spawnattr_t\fP

and \fBposix_spawn_file_actions_t\fP types used in
|
|
performing spawn operations.
|
|
.LP
|
|
The \fI<spawn.h>\fP header shall define the flags that may be set
|
|
in a \fBposix_spawnattr_t\fP object using the \fIposix_spawnattr_setflags\fP()
|
|
function:
