.TH pcprintf 3 2015-07-15 "LIBPIPECOLORS" "Using pcprintf to print colors"
.SH NAME
pcprintf,
pcsprintf \- convert pipecode (|10) to ansi colors
.SH SYNOPSIS
.B #include <pipecolors.h>
.sp
.B using namespace pipecolors;
.sp
.BI "int pcprintf(const char * " format ", ...);"
.br
.BI "int pcsprintf(char * " str ", const char * " format ", ...);"
.sp

.SH DESCRIPTION
The functions in the
.BR pcprintf ()
family produce output according to a
.I format
as described below.
.PP
.SS pcprintf ()
This function parses input exactly like
.BR printf (3)
the only difference is that it converts old renegade bbs style pipecodes (|10) to ansi sequences.

See NOTES.
.PP
.SS pcsprintf ()
This function parses input exactly like
.BR sprintf (3)
the only difference is that it converts old renegade bbs style pipecodes (|10) to ansi sequences.

See NOTES.
.SS Return value
Upon successful return, these functions return the number of characters
printed (excluding the null byte used to end output to strings and
.I including
the ansi color code e.g. \fBx1b[0;39m\fR).

If an output error is encountered, a negative value is returned.
.SS Format of the format string

See
.BR printf (3)

.SS The flag characters
See
.BR printf (3)

.SH CONFORMING TO
The
.BR pcprintf (),
and
.BR pcsprintf ()
functions conform to C99 as they essentially wrap
.BR printf (3)
and
.BR sprintf (3)
.
.SH NOTES
.BR pcprintf ()
and
.BR pcsprintf ()
use
.BR vasprintf (3)
to automatically allocate buffer memory.

.SH BUGS
See
.BR printf (3)

.SH EXAMPLE
.nf
#include <\fBcstdio\fR>
#include <\fBiostream\fR>
#include <\fBpipecolors.h\fR>

using \fBnamespace\fR pipecolors;

\fBint\fR main(\fBvoid\fR) {

   \fBint\fR num = 5;
   \fBconst char*\fR str = "My number is";
   pcprintf("|02%s |10%d|39\\n", str, num);

   \fBreturn\fR 0;
}

\fBOutput\fR "\fB[ESC]\fRx1b[0;32mMy number is \fB[ESC]\fRx1b[0;92m5\fB[ESC]\fRx1b[0;39m";
.P
This would print \fBMy Number is\fR in dark green and \fI5\fR in light green.
The final code \fB|39\fR resets to the default color.
