Prints font-based text in graphics mode.
#include <graph.h>
void __far _outgtext( const char__far *text );
| text | Text string to output |
The _outgtext function outputs on the screen the null-terminated string that text points to. The text is output using the current font at the current graphics position and in the current color.
No formatting is provided, in contrast to the standard console I/O library routines such as printf.
After it outputs the text, _outgtext updates the current graphics position.
The _outgtext function operates only in graphics video modes (e.g., _MRES4COLOR). Because it is a graphics function, the color of text is set by the _setcolor function, not by the _settextcolor function. Similarly, the position is affected by the _moveto function, not by the _settextposition function.
None.
