cr_perror(3)

DESCRIPTION

cr_perror() prints to standard error an error or warning message corresponding to error, which should be the return value from an immediately previous call to one of the libcrash calls. The message describes the problem that occurred, explains its implications when appropriate, and gives corrective action where appropriate.

If called with a zero error value, indicating success, cr_perror() prints nothing. Therefore, it can be called after each libcrash call without harm. (If called after cr_verify() with the CR_ERRORMSGS flag set, repeated error messages may result.)

crash_cb should be the same crash dump descriptor as was passed to the call that returned error. If the call was cr_open(), pass the crash dump descriptor returned by that call, even if it is NULL.

If error is CRERR_ERRNO, indicating that the system variable errno contains the error information, cr_perror() will refer to errno to print the appropriate message. In these cases it is critical that cr_perror() be called immediately after the offending libcrash call returns.
