Description
iprintf, fiprintf, siprintf, sniprintf, asiprintf, and asniprintf are the same as printf, fprintf, sprintf, snprintf, asprintf, and asnprintf, respectively, except that they restrict usage to non-floating-point format specifiers.

_iprintf_r, _fiprintf_r, _asiprintf_r, _siprintf_r, _sniprintf_r, _asniprintf_r are simply reentrant versions of the functions above.

Returns
Similar to printf, fprintf, sprintf, snprintf, asprintf, and asnprintf.

Portability
iprintf, fiprintf, siprintf, sniprintf, asiprintf, and asniprintf are newlib extensions.

Supporting OS subroutines required: close, fstat, isatty, lseek, read, sbrk, write.
