DESCRIPTION

Handle signals via a more elegant C++ interface (e.g., doesn't require the use of global variables or global functions in an application).

Initialization and termination methods.

ACE_Sig_Set (sigset_t *sigset);

Initialize sigset_ with sigset. If sigset == 0 then fill the set.

ACE_Sig_Set (ACE_Sig_Set *sigset);

Initialize sigset_ with sigset. If sigset == 0 then fill the set.

ACE_Sig_Set (int fill = 0);

If fill == 0 then initialize the sigset_ to be empty, else full.

~ACE_Sig_Set (void);

int empty_set (void);

Create a set that excludes all signals defined by the system.

int fill_set (void);

Create a set that includes all signals defined by the system.

int sig_add (int signo);

Adds the individual signal specified by signo to the set.

int sig_del (int signo);

Deletes the individual signal specified by signo from the set.

int is_member (int signo) const;

Checks whether the signal specified by signo is in the set.

operator sigset_t *();

Returns a pointer to the underlying sigset_t.

sigset_t sigset (void) const;

Returns a copy of the underlying sigset_t.

void dump (void) const;

Dump the state of an object.

ACE_ALLOC_HOOK_DECLARE;

Declare the dynamic allocation hooks.
