The [] is the scanset character. [^\n] tells that while the input is not a
newline ('\n') take input. Then with the %*c it reads the newline character
from the input buffer (which is not read), and the * indicates that this read
in input is discarded (assignment suppression), as you do not need it, and this
newline in the buffer does not create any problem for next inputs that you might take.
Read here about the scanset and the assignment suppression operators.
Note you can also use gets but ....
Never use gets(). Because it is impossible to tell without knowing the data in
advance how many characters gets() will read, and because gets() will continue
to store characters past the end of the buffer, it is extremely dangerous to use.
It has been used to break computer security. Use fgets() instead.

/* > */
/* > Those columns which have two '*'s can be handled by SROT. */
/* > Those columns which have no '*'s can be ignored, since as long */
/* > as the Givens rotations are carefully applied to preserve */
/* > symmetry, their values are determined. */
/* > Those columns which have one '*' have to be handled separately, */
/* > by using separate variables "p" and "q": */

/* > */
/* > The element p would have to be set correctly, then that column */
/* > is rotated, setting p to its new value. The next call to */
/* > CLAROT would rotate columns j and j+1, using p, and restore */

Routine Description:
Send log message through wireless event
Support standard iw_event with IWEVCUSTOM. It is used below.
iwreq_data.data.flags is used to store event_flag that is defined by user.
iwreq_data.data.length is the length of the event log.
The format of the event log is composed of the entry's MAC address and
the desired log message (refer to pWirelessEventText).
ex: 11:22:33:44:55:66 has associated successfully
p.s. The requirement of Wireless Extension is v15 or newer.

/*
This is a simple texinfo to man page converter. It needs some
special markup in th e texinfo and tries best to get a create man
page. It has been designed for the GnuPG man pages and thus only
a few texinfo commands are supported.
To use this you need to add the following macros into your texinfo
source:
@macro manpage {a}
@end macro
@macro mansect {a}
@end macro
@macro manpause
@end macro
@macro mancont
@end macro
They are used by yat2m to select parts of the Texinfo which should
go into the man page. These macros need to be used without leading
left space. Processing starts after a "manpage" macro has been
seen. "mansect" identifies the section and yat2m make sure to
emit the sections in the proper order. Note that @mansect skips
the next input line if that line begins with @section, @subsection or
@chapheading.
To insert verbatim troff markup, the following texinfo code may be
used:
@ifset manverb
.B whateever you want
@end ifset
alternativly a special comment may be used:
@c man:.B whatever you want
This is useful in case you need just one line. If you want to
include parts only in the man page but keep the texinfo
translation you may use:
@ifset isman
stuff to be rendered only on man pages
@end ifset
or to exclude stuff from man pages:
@ifclear isman
stuff not to be rendered on man pages
@end ifclear
the keyword @section is ignored, however @subsection gets rendered
as ".SS". @menu is completely skipped. Several man pages may be
extracted from one file, either using the --store or the --select
option.
If you want to indent tables in the source use this style:
@table foo
@item
@item
@table
@item
@end
@end
Don't change the indentation within a table and keep the same
number of white space at the start of the line. yat2m simply
detects the number of white spaces in front of an @item and remove
this number of spaces from all following lines until a new @item
is found or there are less spaces than for the last @item.
