printf
(foldoc) | printf
The standard function in the C programming
language library for printing formatted output.
The first argument is a format string which may contain
ordinary characters which are just printed and "conversion
specifications" - sequences beginning with '%' such as %6d
which describe how the other arguments should be printed, in
this case as a six-character decimal integer padded on the
right with spaces.
Possible conversion specifications are d, i or u (decimal
integer), o (octal), x, X or p (hexadecimal), f
(floating-point), e or E (mantissa and exponent,
e.g. 1.23E-22), g or G (f or e format as appropriate to the
value printed), c (a single character), s (a string), %
(i.e. %% - print a % character). d, i, f, e, g are signed,
the rest are unsigned.
The variant fprintf prints to a given output stream and
sprintf stores what would be printed in a string variable.

debugging by printf
(foldoc) | debugging by printf
The debugging technique where the programmer
inserts print statements into a program so that when run the
program leaves a "trail of breadcrumbs" allowing him to see
which parts were executed. The information output may just be
a short string to indicate that a particular point in the code
has been reached or it might be a complete stack trace. The
output typically just goes to the window or terminal in which
the program is running or may be written to a log file.
printf is the standard C print function, other languages
would use different names.

load-bearing printf
(foldoc) | load-bearing printf
The kind of bug present in a program
which works correctly when producing debug output but fails when
the debugging is turned off.
The expression combines {load-bearing wall
(http://en.wikipedia.org/wiki/The_Builders)} and printf as used
in debugging by printf.
