Library heap usage requirements of microlib

2.3 Library heap usage requirements of microlib

Library heap usage requirements for microlib differ to those of standardlib.

The differences are:
  • The size of heap memory allocated for fopen() is 20 bytes for the FILE structure.
  • No buffer is ever allocated.
You must not declare main() to take arguments if you are using microlib.

Note

The size of heap memory allocated for fopen() might change in future releases.
