NAME
|
|
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""
