Apply Brew MP Best Practices to Avoid Memory
Corruptions
• The performance of a ‘crashed’ system is ZERO
• Release all BMP API’s through IQI_RELEASEIF().IQI_RELEASEIF
– Ensures only memory of a non-null null API pointer is released
– After the release the pointer will be set to NULL
• All the FREE() should be replaced with FREEIF()
– FREEIF() will ensure that only memory of a non-null null pointer is freed
– After the free, the pointer will be set to NULL
• Only use the version of the helper functions that accept “size” as one its
parameters for boundary checking. This includes functions like strncpy,
snprintf, etc… This will avoid any possible buffer-overrun.
