PDCurses Description:
|

PDCurses Return Value:
|
||||
This routine will return OK upon success and otherwise ERR will
|
||||
be returned.
|
||||
|
||||
PDCurses Errors:
|
||||
It is an error to pass a NULL WINDOW pointer.

PDC_chg_attr_pair() - Writes character and attribute to physical screen
|
||||
|
||||
PDCurses Description:
|
||||
This is a private PDCurses function.
|

|

Writes a single character 'chr' with attribute 'attr' to the
|

current cursor location.
|

NOTE: Though passed as 16 bit quantities, only the lower 8 bits
|

will be used to create a character/attribute pair.

PDCurses Return Value:

This function returns OK on success and ERR on error.

No errors are defined for this function under DOS.
