bsdproc(3C)bsdproc(3C)NAME
bsdproc: killpg(), getpgrp(), setpgrp(), signal(), sigvec() - 4.2 BSD-
compatible process control facilities
SYNOPSIS
Obsolescent Interfaces
DESCRIPTION
These calls simulate (and are provided for backward compatibility with)
functions of the same name in the 4.2 Berkeley Software Distribution.
This version of is equivalent to the system call (see setpgid(2)).
This version of is equivalent to the system call (see getpid(2)).
is equivalent to the system call (see kill(2)).
The function is no longer supported. Please see the manpage for sigac‐
tion(2).
This version of has the same effect as , where vec−>sv_handler is equal
to func, vec−>sv_mask is equal to 0, and vec−>sv_flags is equal to 0.
returns the value that would be stored in ovec−>sv_handler if the
equivalent call would have succeeded. Otherwise, returns −1 and is set
to indicate the reason as it would have been set by the equivalent call
to
For applications that use BSD signal, it is recommended that they use
sigaction(2). The system supports an alternative with similar behavior
to Berkeley Software Distribution, and the API is but its use is not
recommended.
WARNINGS
While the 4.3 BSD release defined extensions to some of the interfaces
described here, only the 4.2 BSD interfaces are emulated by this pack‐
age.
should not be used in conjunction with the facilities described under
sigset(3C).
Obsolescent Interfaces
The function is no longer supported. Please see the manpage for sigac‐
tion(2).
APPLICATION USAGE
Threads Considerations
The signal disposition (such as catch/ignore/default) established by
and is shared by all threads in the process.
