DESCRIPTION
|
|
<<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>,
|
|
<<asiprintf>>, are the same as <<printf>>, <<fprintf>>,
|
|
<<sprintf>>, <<snprintf>>, and <<asprintf>>, respectively,
|
|
only that they restrict usage to non-floating-point format
|
|
specifiers.
|
|
|
|
RETURNS
|
|
<<siprintf>> and <<asiprintf>> return the number of bytes in the output string,
|
|
save that the concluding <<NULL>> is not counted.
|
|
<<iprintf>> and <<fiprintf>> return the number of characters transmitted.
|
|
If an error occurs, <<iprintf>> and <<fiprintf>> return <<EOF>> and
|
|
<<asiprintf>> returns -1. No error returns occur for <<siprintf>>.
|
|
|
|
PORTABILITY
|
|
<<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>, and <<asprintf>>
|
|
are newlib extensions.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
