Function Documentation

cwist_error_is_ok_extern()

bool cwist_error_is_ok_extern

(

const cwist_error_t *

err

)

Out-of-line cwist_error_is_ok(); see include/cwist/sys/err/cwist_err.h.

Out-of-line cwist_error_is_ok(); see include/cwist/sys/err/cwist_err.h.

Forwards to the inline helper so the two can never disagree. Success means the active channel holds its zero/empty value; NULL counts as success and an unknown errtype counts as failure.

Parameters

err	Error object to test (may be NULL).

Returns

true when err represents success.

make_error()

cwist_error_t make_error

(

cwist_errtype_t

type

)

Creates an error object initialized with the specified type.

Parameters

type	The type of error to create.

Returns

Initialized cwist_error_t structure.

Creates an error object initialized with the specified type.

Parameters

type	Error payload discriminator to store in the result.

Returns

Error value with errtype set and the payload left for the caller to fill.
