 For example, an idiomatic way to manage dynamic memory in C would be to use the C standard library functions "malloc" and "free".Such code would be well intelligible to somebody familiar with C, and would be unlikely to cause issues with software portability to different computing platforms.On the other hand, if the code would forgo the use of these standard functions, and instead request memory using the system call sbrk to achieve some special behaviour, that could be considered non-idiomatic; it would require more effort to understand and not be portable to non-Unix-like systems.
