# fmt\_uint(3diet)

write an ASCII representation of an unsigned integer

## NAME

fmt\_uint - write an ASCII representation of an unsigned integer

## SYNTAX

**#include \<fmt.h\>**

size\_t **fmt\_uint**(char \**dest*,unsigned int *source*);

## DESCRIPTION

fmt\_uint writes an ASCII representation ('0' to '9', base 10) of *source* to *dest* and returns the number of bytes written.

fmt\_uint does not append \\0.

If *dest* equals FMT\_LEN (i.e. is zero), fmt\_uint returns the number of bytes it would have written.

For convenience, fmt.h defines the integer FMT\_ULONG to be big enough to contain every possible fmt\_uint output plus \\0.
