Description:
Header file:
Return value:
Parameters:
384
Example:
The functions ovfsubc, ovfsubw, and ovfsubl subtract signed 1-byte, 2-byte,
and 4-byte data dst and src, respectively (dst-src). The functions ovfsubuc,
ovfsubuw, and ovfsubul subtract unsigned 1-byte, 2-byte, and 4-byte data
dst and src, respectively.
Then, these functions store the results to the area specified by rst only
when rst is not 0, and return 0 when the results do not overflow or return
a value other than 0 when they do overflow.
These functions can be used only in the conditional statements such
as if, do , while, and for statements.
The ovfsubl and ovfsubul functions are valid when the CPU is other than
H8/300.
