Program termination
The following functions manage program termination and resource cleanup.
| Defined in header <stdlib.h> | |
|---|---|
| causes abnormal program termination (without cleaning up) (function) | |
| causes normal program termination with cleaning up (function) | |
| (C11) | causes normal program termination without completely cleaning up (function) |
| (C99) | causes normal program termination without cleaning up (function) |
registers a function to be called on exit() invocation (function) | |
| (C11) | registers a function to be called on quick_exit invocation (function) |
| indicates program execution execution status (macro constant) | |
Communicating with the environment
| calls the host environment's command processor (function) | |
| (C11) | access to the list of environment variables (function) |
Signals
Several functions and macro constants for signal management are provided.
| Defined in header <signal.h> | |
|---|---|
| sets a signal handler for particular signal (function) | |
| runs the signal handler for particular signal (function) | |
| the integer type that can be accessed as an atomic entity from an asynchronous signal handler (typedef) | |
| defines signal handling strategies (macro constant) | |
| error was encountered (macro constant) | |
Signal types | |
| defines signal types (macro constant) | |
Non-local jumps
| Defined in header <setjmp.h> | |
|---|---|
| saves the context (function macro) | |
| jumps to specified location (function) | |
Types | |
| execution context type (function) | |
