They differ only in -restricting the caller to use non-floating-point format specifiers. +<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>>, +<<vsniprintf>>, and <<vasniprintf>> are (respectively) variants of +<<iprintf>>, <<fiprintf>>, <<asiprintf>>, <<siprintf>>, <<sniprintf>>, +and <<asniprintf>>. They differ only in allowing their caller to pass +the variable argument list as a <<va_list>> object (initialized by +<<va_start>>) rather than directly accepting a variable number of +arguments. The caller is responsible for calling <<va_end>>. + +<<_viprintf_r>>, <<_vfiprintf_r>>, <<_vasiprintf_r>>, +<<_vsiprintf_r>>, <<_vsniprintf_r>>, and <<_vasniprintf_r>> are +reentrant versions of the above. 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. +All of these functions are newlib extensions. Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>, <<lseek>>, <<read>>, <<sbrk>>, <<write>>. |
