NAME
fscan - scan a file for possible assignment to variables
SYNOPSIS
fscan(fs, x_1, x_2, ..., x_n)
TYPES
fs file stream open for reading
x_1, x_2, ... any
return integer
DESCRIPTION
Starting at the current position on fs and while values remain in the
x_i arguments, fields of non-whitespace characters are read and evaluated
in succession and if the corresponding x_i is an lvalue, the value of
the field is assigned to x_i. Scanning ceases when no x_i remain or
when the stream reaches end-of-file.
The function returns the number of fields evaluated.
EXAMPLE
; global a, b, c, d;
; f = fopen("/tmp/junk", "w+");
; fputs(f, "\t3+4\t\ta-2i d=a^2 'word'")
; rewind(f)
; fscan(f, a, b, , c)
4
; print a, b, c, d
