config STDIO_DISABLE_BUFFERING
bool "Disable STDIO Buffering"
default n
---help---
Tiny systems may need to disable all support for I/O buffering in
order to minimize the memory footprint.
NOTE that even if STDIO buffering is enabled, you can still disable
buffering by setting CONFIG_STDIO_BUFFER_SIZE=0 or dynamically
through the setvbuf() interface. In this case, however, memory
used for buffering will be eliminated, of course, but there will be
no reduction in static code size. Only setting
CONFIG_STDIO_DISABLE_BUFFERING will reduce static code size.
The setvbuf() interface is not available if
CONFIG_STDIO_DISABLE_BUFFERING is selected.
if !STDIO_DISABLE_BUFFERING
config STDIO_BUFFER_SIZE
int "STDIO buffer size"
default 64
---help---
Size of buffers using within the C buffered I/O interfaces (printf,
putchar, fwrite, etc.). This function sets the initial I/O buffer
size. Zero disables I/O buffering initially. Any buffer size may
be subsequently modified using setvbuf().
config STDIO_LINEBUFFER
bool "STDIO line buffering"
default y
---help---
Sets the default behavior to flush buffered I/O whenever a newline
character is found in the output data stream. This setting just
sets the initial default behavior of all streams. The behavior of
an individual stream can be changed via setvbuf().
endif # !STDIO_DISABLE_BUFFERING
config NUNGET_CHARS
int "Number unget() characters"

config NOPRINTF_FIELDWIDTH
bool "Disable sprintf support fieldwidth"
default n
---help---
sprintf-related logic is a little smaller if we do not support field
widths.
config LIBC_FLOATINGPOINT
bool "Enable floating point in printf"
default n
---help---
By default, floating point
support in printf, sscanf, etc. is disabled.
config LIBC_LONG_LONG
bool "Enable long long support in printf"
default y if !DEFAULT_SMALL
default n if DEFAULT_SMALL
---help---
Enables support for long long formats in printf, sscanf, etc. is
enabled. This is enabled by default but if you are trying to
reduce the FLASH footprint, then disabling this feature is one
option. The FLASH saves comes not from disabling the long long
formats, but rather from omitting the large long long arithmetic
libraries that will be drawn into the build if long long support
is enabled.

bool "Scanset support"
default n
---help---

default EOL_IS_EITHER_CRLF
---help---
This selection determines the line terminating character that is used.

both. If not specified, the default is either CR or LF (but not both)
as the line terminating charactor.
