|---|
| 1 | At this stage printf is very young and limited, as it hopefully
|
|---|
| 2 | will be developed along with BDSH. Functionality is heavily related
|
|---|
| 3 | on libc printf already available. BDSH printf implements only 3 format
|
|---|
| 4 | flags, with no options/precision/width modifiers allowed. Also,
|
|---|
| 5 | one output control is available - '\n'. '\' character stands
|
|---|
| 6 | as an escape character, i.e. every special character after it
|
|---|
| 7 | will be treated as general char and will be printed out.
|
|---|
| 8 | What's missing:
|
|---|
| 9 | * Error checking for format string.
|
|---|
| 10 | * Add more output controls (\t \r ...)
|
|---|
| 11 | * Add width/precision options for number printings
|
|---|
| 12 | * Add more format flags (%f %b ...)
|
