DESCRIPTION
|
|
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>> and
|
|
<<vsniprintf>> are (respectively) variants of <<iprintf>>, <<fiprintf>>,
|
|
<<asiprintf>>, <<siprintf>>, and <<sniprintf>>. They differ only in
|
|
restricting the caller to use non-floating-point format specifiers.
|
|
|
|
RETURNS
|
|
The return values are consistent with the corresponding functions:
|
|
<<vasiprintf>>/<<vsiprintf>> returns the number of bytes in the output string,
|
|
save that the concluding <<NULL>> is not counted.
|
|
<<viprintf>> and <<vfiprintf>> return the number of characters transmitted.
|
|
If an error occurs, <<viprintf>> and <<vfiprintf>> return <<EOF>> and
|
|
<<vasiprintf>> returns -1. No error returns occur for <<vsiprintf>>.
|
|
|
|
PORTABILITY
|
|
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>> and <<vsniprintf>>
|
|
are newlib extensions.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
