logger_log() specifications

Signature

logger_status_t logger_log(logger_t *l, const char *message);

Purpose

Emit the message message through the logger port.

Preconditions

• If l != NULL, l must point to a valid logger_t handle created by logger_create().

Invalid arguments

• l must not be NULL.
• message must not be NULL.

Success

• Delegates the log operation to the adapter-facing log callback stored in the logger handle.
• Returns the value produced by the underlying log callback.

Failure

• If l == NULL, returns LOGGER_STATUS_INVALID.
• If message == NULL, returns LOGGER_STATUS_INVALID.

Notes

• logger_log() exposes the borrower-facing logging operation of the logger port.
• This function requires a logger handle whose adapter-facing virtual table has been validated at creation time by logger_create().
