Help¶

Build cbprintf with buffers sized to support converting integer values with no more than 32 bits.

This will decrease stack space, but affects conversion of any type with more than 32 bits. This includes not only intmax_t but any type that can be converted to an integral represention including size_t and pointers.

With CBPRINTF_COMPLETE conversions that may result in value-specific truncation are not supported, and the generated text will be the specification (e.g. %jd).

With CBPRINTF_NANO all conversions will be attempted but values that cannot fit will be silently truncated.

Direct dependencies¶
