Specifying the Duration of Returned Objects
The database server user-defined routines generally allocate objects in the current duration. For example, a user-defined function return value created with
mi_new_var()
is allocated
PER_FUNCTION
. If a function does not follow this rule, the function reference page indicates the duration of returned values.
To increase the allocation duration, use
mi_switch_memory_duration()
before the function call that creates the return value.
To allocate your own objects, use
mi_alloc()
for the current duration or
mi_dalloc()
for a specific duration.
