CONFIG_CBPRINTF_REDUCED_INTEGRAL

Convert only integer values that fit in 32 bits

Type: bool

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
