Hi,

wer kann mir bei dem folgenden Problem helfen ?

----------------------------------------------------
sigsetmask.c:31: parse error before `sigsetmask'
sigsetmask.c:32: parse error before `*'
sigsetmask.c: In function `sigsetmask':
sigsetmask.c:34: `sigset_t' undeclared (first use this function)
sigsetmask.c:34: (Each undeclared identifier is reported only once
sigsetmask.c:34: for each function it appears in.)
sigsetmask.c:34: parse error before `old'
sigsetmask.c:36: `SIG_SETMASK' undeclared (first use this function)
sigsetmask.c:36: `set' undeclared (first use this function)
sigsetmask.c:36: `old' undeclared (first use this function)
------------------------------------------------------
Wir haben auf unserem System (ESIX SysV 3.2) alles nach sigset_t
und SIG_SETMASK durchsucht. 
Wo und wie sind die normalerweise deklariert ?

Danke fuer Eure Hilfe

Auf unserm System (SunOS 4.1.2) sieht das folgendermassen aus:

in signal.h:
	...
	#define SIG_SETMASK 0x0004
	...
	#include <sys/stdtypes.h>	/* for sigset_t */
	...

in sys/stdtypes.h:
	...
	typedef int sigset_t;
	...

Dazu ist in der POSIX Norm folgendes zu lesen:

(nach ISO/IEC 9945-1:1990)

3.3.1.1 Signal Names

[...] The type sigset_t is used to represent set of signals. It is
always an integral or structure type. Several functions used to
manipulate objects of type sigset_t are defined in 3.3.3.

[...]

3.3.5 Examine and Change Blocked Signals

Function: sigprocmask()

3.3.5.1 Synopsis

#include <signal.h>

int sigprocmask(int how, const sigset_t *set, sigset_t *oset);

3.3.5.2 Description

The sigprocmask() function is used to examine or change (or both) the
signal mask of the calling process. If the value of the argument set
is not NULL, it points to a set of signals to be used to change the
currently blocked set.

The value of the argument how indicates the manner in which the set is
changed and shall consist of one of the following values, as defined
in the header <signal.h>:

NAME		DESCRIPTIOM
SIG_BLOCK	The resulting set shall be the union of the current
		set and the signal set pointed to by the argument set.
SIG_UNBLOCK	The resulting set shall be the intersection of the
		current set and the complement of the signal set
		pointed to by the argument set.
SIG_SETMASK	The resulting set shall be the signal set pointed to
		by the argument SET
[...]


In der Beziehung sollte ein SysV POSIX kompatibel sein und ueber ein
konformes <signal.h> verfuegen.

Ich hoffe das hilft dir weiter....
