If I set a variable within a while-read loop, sometimes it's local to the loop, sometimes it's global, depending on how the loop is set up. I'm testing this on a Debian Lenny system using both bash and dash with the same results.
For example:

Heyas
Figured me had a 'typo' in tui-conf-set, i went to fix it.
Now, i also figured, it might be nice to have tui-conf-set report (to console, not only exit code) wether it could save the variable to the file or not.
This said, I appended this code: (the tui-title and tui-echo lines are... (3 Replies)

fparseln
FPARSELN(3) BSD Library Functions Manual FPARSELN(3)
NAME
fparseln -- return the next logical line from a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
char *
fparseln(FILE *stream, size_t *len, size_t *lineno, const char delim[3], int flags);
DESCRIPTION
The fparseln() function returns a pointer to the next logical line from the stream referenced by stream. This string is NUL terminated and
it is dynamically allocated on each invocation. It is the responsibility of the caller to free the pointer.
By default, if a character is escaped, both it and the preceding escape character will be present in the returned string. Various flags
alter this behaviour.
The meaning of the arguments is as follows:
stream The stream to read from.
len If not NULL, the length of the string is stored in the memory location to which it points.
lineno If not NULL, the value of the memory location to which is pointed to, is incremented by the number of lines actually read from the
file.
delim Contains the escape, continuation, and comment characters. If a character is NUL then processing for that character is disabled. If
NULL, all characters default to values specified below. The contents of delim is as follows:
delim[0] The escape character, which defaults to , is used to remove any special meaning from the next character.
delim[1] The continuation character, which defaults to , is used to indicate that the next line should be concatenated with the
current one if this character is the last character on the current line and is not escaped.
delim[2] The comment character, which defaults to #, if not escaped indicates the beginning of a comment that extends until the end
of the current line.
flags If non-zero, alter the operation of fparseln(). The various flags, which may be or-ed together, are:
FPARSELN_UNESCCOMM Remove escape preceding an escaped comment.
FPARSELN_UNESCCONT Remove escape preceding an escaped continuation.
FPARSELN_UNESCESC Remove escape preceding an escaped escape.
FPARSELN_UNESCREST Remove escape preceding any other character.
FPARSELN_UNESCALL All of the above.
RETURN VALUES
Upon successful completion a pointer to the parsed line is returned; otherwise, NULL is returned.
The fparseln() function uses internally fgetln(3), so all error conditions that apply to fgetln(3), apply to fparseln(). In addition
fparseln() may set errno to [ENOMEM] and return NULL if it runs out of memory.

HISTORY
The fparseln() function first appeared in NetBSD 1.4.
