Man page for WCOREDUMP says:
|
|
|
1bdc94 |
|
|
|
1bdc94 |
WCOREDUMP(wstatus) returns true if the child produced a core dump.
|
|
|
1bdc94 |
This macro should be employed only if WIFSIGNALED returned true.
|
|
|
1bdc94 |
|
|
|
1bdc94 |
This macro is not specified in POSIX.1-2001 and is not
|
|
|
1bdc94 |
available on some UNIX implementations (e.g., AIX, SunOS). Therefore,
|
|
|
1bdc94 |
enclose its use inside #ifdef WCOREDUMP ... #endif.
|
|
|
1bdc94 |
|
|
|
1bdc94 |
Let's do exactly this.
