◆ check_buffer_size()

static void check_buffer_size	(	PLmDev *	dev,
		size_t	need_size
	)

static

Definition at line 408 of file plmetafile.c.

◆ plreadmetafile()

void plreadmetafile ( char * infile )

Reads a PLplot metafile and uses the current plot stream to display the contents. If the plot stream has not been initialized, this routine will attempt to intialize the plot stream via a plinit() call. For an initialized plot stream, the metafile will start at the current page/subpage.

Parameters

infile Input PLplot metafile name.

Pass NULL for infile to use the filename passed from the command line option -mfi.

Returns void
