Hi,
Even with null context it does not turn to ereport, and returns dummy value -
#define errsave_domain(context, domain, ...) \
do { \
struct Node *context_ = (context); \
pg_prevent_errno_in_scope(); \
if (errsave_start(context_, domain)) \
__VA_ARGS__, errsave_finish(context_, __FILE__, __LINE__, __func__); \
} while(0)
#define errsave(context, ...) \
errsave_domain(context, TEXTDOMAIN, __VA_ARGS__)
/*
* "ereturn(context, dummy_value, ...);" is exactly the same as
* "errsave(context, ...); return dummy_value;". This saves a bit
* of typing in the common case where a function has no cleanup
* actions to take after reporting a soft error. "dummy_value"
* can be empty if the function returns void.
*/
#define ereturn_domain(context, dummy_value, domain, ...) \
do { \
errsave_domain(context, domain, __VA_ARGS__); \
return dummy_value; \
} while(0)
#define ereturn(context, dummy_value, ...) \
ereturn_domain(context, dummy_value, TEXTDOMAIN, __VA_ARGS__)
