NAME
|
|
fgetstr - read the next null-terminated string from a file
|
|
|
|
SYNOPSIS
|
|
fgetstr(fs)
|
|
|
|
TYPES
|
|
fs file stream open for reading
|
|
|
|
return string, null or error value
|
|
|
|
DESCRIPTION
|
|
If the stream is at end of file, the null value is returned.
|
|
|
|
If the stream cannot be read, an error value is returned.
|
|
|
|
Otherwise the function returns the string of characters from the
|
|
current file position to the first null character ('\0') (the file
|
|
position for further reading then being immediately after the '\0'),
|
|
or if no null character is encountered, the string of characters to
|
|
the end of file (the string as usual being terminated by '\0').
|
|
|
|
If the stream being read is from stdin (i.e. files(0)), the
|
|
characters entered are not displayed and reading ends when a '\0' is
|
|
entered (on many terminals this is by ctrl-@).
