- .SH SYNOPSIS
- .LP
- .nf
- #include <spawn.h>
- .fi
- .SH DESCRIPTION
- The
- .IR <spawn.h>
- header shall define the
- .BR posix_spawnattr_t
- and
- .BR posix_spawn_file_actions_t
- types used in performing spawn operations.
- .P
- The
- .IR <spawn.h>
- header shall define the
- .BR mode_t
- and
- .BR pid_t
- types as described in
- .IR <sys/types.h> .
- .P
- The
- .IR <spawn.h>
- header shall define the
- .BR sigset_t
- type as described in
- .IR <signal.h> .
- .P
- The tag
- .BR sched_param
- shall be declared as naming an incomplete structure type, the contents
- of which are described in the
- .IR <sched.h>
- header.
- .P
- The
- .IR <spawn.h>
- header shall define the following symbolic constants for use as the
- flags that may be set in a
- .BR posix_spawnattr_t
- object using the
- \fIposix_spawnattr_setflags\fR()
- function:
- .P
- .nf
- POSIX_SPAWN_RESETIDS
- POSIX_SPAWN_SETPGROUP
- POSIX_SPAWN_SETSCHEDPARAM
- POSIX_SPAWN_SETSCHEDULER
- POSIX_SPAWN_SETSIGDEF
- POSIX_SPAWN_SETSIGMASK
- .fi
- .P
- The following shall be declared as functions and may also be defined
- as macros. Function prototypes shall be provided.
