fmt_strm (3)

#include <fmt.h>

size_t fmt_strm(char *dest,const char *source, ...);

fmt_strm copies all leading nonzero bytes from source and following function arguments to dest and returns the number of bytes it copied.

fmt_strm does not append \0.

If dest equals FMT_LEN (i.e. is zero), fmt_str returns the number of bytes it would have written, i.e. the number of leading nonzero bytes of source and following function arguments.
