rockbox/firmware/common/fdprintf.c, branch duke3d My Rockbox tree Add a small 32-byte write buffer to fdprintf. 2017-11-28T14:01:17+00:00 Michael Sevakis jethead71@rockbox.org 2017-11-28T13:06:30+00:00 055e2115de90893b01c8214cee805ae5fd669a7c Avoids a call to write() for every output character. It doesn't need to be very large to have a great effect on speed and realize most of the potential. Change-Id: I11820c1968ed7b20aa00e106a022c1b864b03d21

Implement a much more capable vuprintf() 2017-11-21T10:00:27+00:00 Michael Sevakis jethead71@rockbox.org 2017-09-08T23:28:02+00:00 5c9688961ef9166cec5225db50d5f73691d8292d New support as well as some buggy support fixed. Still no floating point support if ever that would be desired. Support (*): * Flags: '-', '+', ' ', '#', '0' * Width and precision: 'n', '.n', '*' and '.*' * Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z' * Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X' (*) Provision exists to switch lesser-used stuff on or off or when certain functionality isn't desired (bootloader?). The compulsory radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length modifiers being optional. The default setup is 'l', 'z', 'c', 'd', 'p/P', 's', 'u', 'x/X'. * Move fdprintf() to its own file. It was in a strange place. * Make callers compatible and fix a couple snprintf() bugs while at it. Could smush it down in size but I'm gonna get over the binsize neurosis and just the let optimizer do its thing. Change-Id: Ibdc613a9b6775802c188b29b9dd46c568c94f7c3

Support (*):
* Flags: '-', '+', ' ', '#', '0'

* Width and precision: 'n', '.n', '*' and '.*'

* Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z'

* Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X'

(*) Provision exists to switch lesser-used stuff on or off or when
certain functionality isn't desired (bootloader?). The compulsory
radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length
modifiers being optional. The default setup is 'l', 'z', 'c', 'd',
'p/P', 's', 'u', 'x/X'.

* Move fdprintf() to its own file. It was in a strange place.

* Make callers compatible and fix a couple snprintf() bugs while
at it.

Could smush it down in size but I'm gonna get over the binsize
neurosis and just the let optimizer do its thing.
