The <signal.h> header is part of the standard library of the C programming language which provides the functionality necessary for dealing with various signals.
Types[edit]
Type | Description | Since |
---|---|---|
sig_atomic_t | Integer type of an object that can be accessed as an atomic entity | C89 |
Macros[edit]
The header provides the following macro definitions:
Macro Name | Description | Since |
---|---|---|
SIG_DFL | macros expand into integral expressions that compare unequal to the address of any declarable function | C89 |
SIG_ERR | C89 | |
SIG_IGN | C89 | |
SIGABRT | expand to positive integer constant expressions with type int; corresponding to an abnormal termination | C89 |
SIGFPE | expand to positive integer constant expressions with type int; corresponding to an erroneous arithmetic operation | C89 |
SIGILL | expand to positive integer constant expressions with type int; corresponding to a detection of an invalid function image | C89 |
SIGINT | expand to positive integer constant expressions with type int; corresponding to a receipt of an interactive attention signal | C89 |
SIGSEGV | expand to positive integer constant expressions with type int; corresponding to an invalid access to storage | C89 |
SIGTERM | expand to positive integer constant expressions with type int; corresponding to a termination request sent to the program | C89 |
Functions[edit]
Function | Description | Since |
---|---|---|
signal | sets up a signal handler for specific signal | C89 |
raise | carries out the action defined by signal() | C89 |
