fgetfile - read the rest of a file to form a string
SYNOPSIS
fgetfile(fs)
TYPES
fs file stream open for reading
return string or null value
DESCRIPTION
If the current file position for fs is the end of the file, the
null value is returned.
Otherwise the function returns the string formed from reading all
characters from the current file position to the end of the file.
If the content of the file "newfile" is a sequence of statements that
could form the body of function definition, the statement sequence
fs = fopen("newfile", "r");
eval(fgetfile(fs));
achieves the same as the command
read newfile;
EXAMPLE
; f = fopen("/tmp/newfile", "w")
; fputs(f, "abc\0xyz\n\t\xb0\0\r\v123"
; freopen(f, "r")
; estr(fgetfile(f))
""abc\0xyz\n\t\xb0\0\r\v123""
