Detailed Description

Dynamic output buffer (auto-expanding)

Represents a dynamic output buffer that automatically expands when more space is needed. Buffer grows exponentially (doubles in size) to minimize reallocation overhead.

MEMORY MANAGEMENT:

• buf: Points to allocated buffer (NULL if not yet allocated)
• len: Current number of bytes used in buffer
• cap: Current buffer capacity in bytes
• Buffer must be freed by caller using free(buf) when done

Note

Buffer is null-terminated after each append operation.

Buffer grows automatically when space is needed.
