.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm sigpending
|
||
|
|
function returns a mask of the signals pending for delivery
|
||
|
|
to the calling process in the location indicated by
|
||
|
|
.Fa set .
|
||
|
|
Signals may be pending because they are currently masked,
|
||
|
|
or they are in transition before delivery (although the latter case is not
|
||
|
|
normally detectable).
|
||
|
|
.Sh RETURN VALUES
|
||
|
|
A 0 value indicates that the call succeeded.
|
||
|
|
A \-1 return value indicates an error occurred and
|
||
|
|
.Va errno
|
||
|
|
is set to indicate the reason.
|
||
|
|
.Sh ERRORS
|
||
