Description

My application fails to allocate memory after reserving a certain amount of memory from heap. What should I do to allocate more memory from heap?

The EPOCHEAPSIZE directive can be set in the .mmp file to reserve or constrict the amount of procurable heap available to the process during start-up and at run time.

Syntax:

epocheapsize minimum maximum

The minimum value (in bytes, rounded to the nearest 4K) ensures that the process does not start/run unless the device has the specified amount of free memory available.

The maximum value limits the amount of heap the process can consume.
