ignore_handler_s
| Defined in header <stdlib.h>
|
||
| void ignore_handler_s( const char * restrict msg, void * restrict ptr, |
(since C11) | |
The function simply returns to the caller without performing any other action.
A pointer to this function can be passed to set_constraint_handler_s to establish a runtime constraints violation handler that does nothing.
- As with all bounds-checked functions,
ignore_handler_sis only guaranteed to be available if __STDC_LIB_EXT1__ is defined by the implementation and if the user defines __STDC_WANT_LIB_EXT1__ to the integer constant 1 before including<stdlib.h>.

Parameters
| msg | - | pointer to character string that describes the error |
| ptr | - | pointer to an implementation-defined object or a null pointer. Examples of implementation-defined objects are objects that give the name of the function that detected the violation and the line number when the violation was detected |
| error | - | the error about to be returned by the calling function, if it happens to be one of the functions that return errno_t |
Return value
none; this function simply returns to its caller
Notes
If ignore_handler_s is used as a the runtime constraints handler, the violations may be detected by examining the results of the bounds-checked function calls, which may be different for different functions (non-zero errno_t, null character written to the first byte of the output string, etc)
If set_constraint_handler_s is never called, the default handler is implementation-defined: it may be abort_handler_s, ignore_handler_s, or some other implementation-defined handler.
