vfprintf(), vprintf(), and vsprintf()

This is a file I/O function, also hardware dependent. It is not implemented in this Compiler.

Syntax

  #include <stdio.h>

  int vfprintf(FILE *f,

               const char *format,

               va_list args);

  int vprintf(const char *format, va_list args);

  int vsprintf(char *s,

               const char *format,

               va_list args);

Description

These functions are the same as fprintf(), printf(), and sprintf(), except that they take a va_list instead of an open parameter list as argument.

For a detailed format description see sprintf().

Note: Only vsprintf() is implemented, because the other two functions depend on the actual setup and environment of the target.

Return

The number of characters written, if successful; a negative number otherwise.
