Description
Writes a character with an attribute at the specified display
page’s current cursor location, overwriting any character (and
attribute) that may already be there.
After calling this function, call vidPutCursor to move the cursor
to a new position.
To write a character without an attribute, use vidWriteC.
If the application writes to a display page
other than the current one, the written string
does not appear until the application sets
that page as the current one with
vidSetPage. Strings written to the current
page appear immediately.
Syntax
void far vidWriteCA(unsigned char uchChr,
unsigned char uchAttr,
short sCount,
short sPage);
Parameters
uchChr
The ASCII character to write. Bell, backspace,
carriage return, and line feed characters are invalid.
uchAttr The character’s attribute. Values are:
0x07

sCount The number of times to write the character. This
number must be less than or equal to the number of
columns remaining in the current row.
