Most completed and little printf like subsystem for embedded system.

Example of code size now 2 architecture with all features enabled, compiled with -O3 :

Embedded 32 bit ARM : 2268 bytes
Linux X64 : 3690 bytes

• Tested on microprocessor from 8 to 64 bit
• Optional support for floating point number
• Optional support for long long number
• Support for binary number (%b)
• Support for boolean value (%B)
• Support for pointer in hex format (%p/%P)
• Support for size_t C99 argument size
• No library function required
• Parametric function to emit single char
• Configurable using config.h and -DHAVE_CONFIG_H
• 10% fastest than libc functions.
• And much more

The option can be set directly on the compiler command line for example : gcc -DXCFG_FORMAT_LONGLONG=0 -c xformatc.c compile the function without floating point support or inserted in the file config.h and define the symbol HAVE_CONFIG_H on compilation time.

XCFG_FORMAT_LONGLONG Set to 0 to exclude support for long long.

XCFG_FORMAT_STATIC Set to static to reduce stack usage only for mono thread application.

XCFG_FORMAT_FLOAT Set to 0 to exclude support for floating point.

XCFG_FORMAT_FLOAT_PREC Set to 1 to make calculation using float instead of double.
