  71 DESCRIPTION
  72         <<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>,
  73         <<asiprintf>>, and <<asniprintf>> are the same as <<printf>>,
  74         <<fprintf>>, <<sprintf>>, <<snprintf>>, <<asprintf>>, and
  75         <<asnprintf>>, respectively, except that they restrict usage
  76         to non-floating-point format specifiers.
  77
  78         <<_iprintf_r>>, <<_fiprintf_r>>, <<_asiprintf_r>>,
  79         <<_siprintf_r>>, <<_sniprintf_r>>, <<_asniprintf_r>> are
  80         simply reentrant versions of the functions above.
  81
  82 RETURNS
  83 Similar to <<printf>>, <<fprintf>>, <<sprintf>>, <<snprintf>>, <<asprintf>>,
  84 and <<asnprintf>>.
  85
  86 PORTABILITY
  87 <<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>, <<asiprintf>>,
  88 and <<asniprintf>> are newlib extensions.
  89
  90 Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
  91 <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
