SigAction () | |
Default constructor creates SigAction object with null-action. | |
SigAction (C_SIG_HANDLER handler_, SigSet *sig_mask_=0, int flags_=0) | |
Construct a SigAction object with "C" signal handler function. | |
SigAction (C_SIG_HANDLER handler_, int signum_, SigSet *sig_mask_=0, int flags_=0) | |
Construct a SigAction with "C" signal handler function and change program's disposition for signum_ immediately. | |
int | register_action (int signum_, SigAction *oaction_=0) |
Register this object as current disposition for signal signum_, and store old disposition in oaction_, if not NULL. | |
int | restore_action (int signum_, SigAction &oaction_) |
Change object's disposition to oaction_, and install it as current disposition for the signal signum_. | |
int | retrieve_action (int signum_) |
Retrieve current disposition for the signal signum_ into this object. | |
void | action (SIGACTION *sa_) |
Set sigaction structure to sa_. | |
SIGACTION * | action () |
Retrieve current sigaction. | |
void | flags (int new_flags_) |
Set signal flags to new_flags_. | |
int | flags () |
Retrieve current flags. | |
void | mask (SigSet &mask_set_) |
Set new signal mask mask_set_. | |
SigSet | mask () |
Retrieve current signal mask. | |
void | handler (C_SIG_HANDLER sha_) |
Set new signal handler to function pointer sha_. | |
C_SIG_HANDLER | handler () |
Retrieve current signal handler function. | |
operator SIGACTION * () | |
Conversion operator that converts SigAction to a pointer to the internal struct sigaction data member for direct use with C-library functions. | |

Construct a SigAction object with "C" signal handler function.
This constructor doesn't install any actions - it is merely a shell for actiono to be installed for any signal(s). Thus, you can reuse the same object for number of differen signals.
handler_ | "C" signal handler function to call. |
sig_mask_ | Set of signals to block while handler_ is active. |
flags_ | Controls behavior of signal handler (OS-specific: see Available Options: section of documentation). |

Construct a SigAction with "C" signal handler function and change program's disposition for signum_ immediately.
First argument is the "C" function. It cannot be a non-static C++ class member function. This function pretty much simulates C-like approach the the signal handling. For C++ member function approach, see SigHandler & Co.
handler_ | "C" signal handler function to call. |
signum_ | Signal which disposition is to change. |
sig_mask_ | Set of signals to block while handler_ is active. |
flags_ | Controls behavior of signal handler (OS-specific: see Available Options: section of documentation). |

Conversion operator that converts SigAction to a pointer to the internal struct sigaction data member for direct use with C-library functions.
Definition at line 351 of file SigAction.h.
References ASSA::SIGACT, and trace_with_mask.
Register this object as current disposition for signal signum_, and store old disposition in oaction_, if not NULL.
This function installs C_SIG_HANDLER this object represents, thus simulating C-like approach to signal handling.
signum_ | Signal which disposition to install. |
oaction_ | Placeholder for the old disposition. |
Definition at line 359 of file SigAction.h.
References m_sa, ASSA::SIGACT, and trace_with_mask.
Change object's disposition to oaction_, and install it as current disposition for the signal signum_.
signum_ | Signal which disposition to restore. |
oaction_ | Disposition to restore. |
Definition at line 370 of file SigAction.h.
References m_sa, ASSA::SIGACT, and trace_with_mask.
Retrieve current disposition for the signal signum_ into this object.
signum_ | Signal number |
