| DESCRIPTION |
| <<vprintf>>, <<vfprintf>>, <<vsprintf>> and <<vsnprintf>> are (respectively) |
| variants of <<printf>>, <<fprintf>>, <<sprintf>> and <<snprintf>>. 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. |
| |
| RETURNS |
| The return values are consistent with the corresponding functions: |
| <<vsprintf>> returns the number of bytes in the output string, |
| save that the concluding <<NULL>> is not counted. |
| <<vprintf>> and <<vfprintf>> return the number of characters transmitted. |
| If an error occurs, <<vprintf>> and <<vfprintf>> return <<EOF>>. No |
| error returns occur for <<vsprintf>>. |
| |
| PORTABILITY |
| ANSI C requires all three functions. |
| |
| Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>, |
| <<lseek>>, <<read>>, <<sbrk>>, <<write>>. |
