/*
* sprintf.c v1.05+ for LPMud 3.0.52 (+ plus mappings)
*
* An implementation of (s)printf() for LPC, with quite a few
* extensions (note that as no floating point exists, some parameters
* have slightly different meaning or restrictions to "standard"
* (s)printf.) Implemented by Lynscar (Sean A Reith).
*
* This version supports the following as modifiers:
* " " pad positive integers with a space.
* "+" pad positive integers with a plus sign.
* "-" left adjusted within field size.
* NB: std (s)printf() defaults to right justification, which is
* unnatural in the context of a mainly string based language
* but has been retained for "compatability" ;)
* "|" centered within field size.
* "=" column mode if strings are greater than field size. this is only
* meaningful with strings, all other types ignore
* this. columns are auto-magically word wrapped.
* "#" table mode, print a list of '\n' separated 'words' in a
* table within the field size. only meaningful with strings.
* n specifies the field size, a '*' specifies to use the corresponding
* arg as the field size. if n is prepended with a zero, then is padded
* zeros, else it is padded with spaces (or specified pad string).
* "."n precision of n, simple strings truncate after this (if precision is
* greater than field size, then field size = precision), tables use
* precision to specify the number of columns (if precision not specified
* then tables calculate a best fit), all other types ignore this.
* ":"n n specifies the fs _and_ the precision, if n is prepended by a zero
* then it is padded with zeros instead of spaces.
* "@" the argument is an array. the corresponding format_info (minus the
* "@") is applyed to each element of the array.
* "'X'" The char(s) between the single-quotes are used to pad to field
* size (defaults to space) (if both a zero (in front of field
* size) and a pad string are specified, the one specified second
* overrules). NOTE: to include "'" in the pad string, you must
* use "\\'" (as the backslash has to be escaped past the
* interpreter), similarly, to include "\" requires "\\\\".
* The following are the possible type specifiers.
* "%" in which case no arguments are interpreted, and a "%" is inserted, and
* all modifiers are ignored.
* "O" the argument is an LPC datatype.
* "s" the argument is a string.
* "d" the integer arg is printed in decimal.
* "i" as d.
* "c" the integer arg is to be printed as a character.
* "o" the integer arg is printed in octal.
* "x" the integer arg is printed in hex.
* "X" the integer arg is printed in hex (in capitals).
