 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.
+<<vprintf>>, <<vfprintf>>, <<vasprintf>>, <<vsprintf>> and <<vsnprintf>> are 
+(respectively) variants of <<printf>>, <<fprintf>>, <<saprintf>>, <<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,
+<<vasprintf>>/<<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>>.
+If an error occurs, <<vprintf>> and <<vfprintf>> return <<EOF>> and
+<<vasprintf>> returns -1.  No error returns occur for <<vsprintf>>.
 
 PORTABILITY
 ANSI C requires all three functions.
