vsscanf(3S) — DG/UX R4.11



vscanf(3S)                        SDK R4.11                       vscanf(3S)


NAME
       vscanf, vfscanf, vsscanf - convert formatted input of a variable
       argument list

SYNOPSIS
       #include <stdio.h>
       #include <stdarg.h>
       int vscanf(const char *format, valist ap);
       int vfscanf(FILE *stream, const char *format, valist ap);
       int vsscanf(const char *s, const char *format, valist ap);

DESCRIPTION
       vscanf, vfscanf and vsscanf are the same as scanf, fscanf, and sscanf
       respectively, except that instead of being called with a variable
       number of arguments, they are called with an argument list as defined
       by the stdarg.h header file.

       The stdarg.h header file defines the type valist and a set of macros
       for advancing through a list of arguments whose number and types may
       vary.  [See stdarg(5)].

   Errors
       These functions return the number of matched patterns, or return OF
       if an error was encountered.
