NAME¶
fmt_xlong - write a hexadecimal ASCII representation of an unsigned long integer
SYNTAX¶
#include <fmt.h>
size_t
fmt_xlong(char *
dest,unsigned long
source);
DESCRIPTION¶
fmt_xlong writes an ASCII representation ('0' to '9' and 'a' to 'f', base 16) of
source to
dest and returns the number of bytes written.
fmt_xlong does not append \0.
If
dest equals FMT_LEN (i.e. is zero), fmt_xlong returns the number of
bytes it would have written.
For convenience, fmt.h defines the integer FMT_XLONG to be big enough to contain
every possible fmt_xlong output plus \0.
