int ovfshalc(char dst,char *rst)
int ovfshalw(int dst,int *rst)
int ovfshall(long dst,long *rst)
Description:
Header:
Return value:
Parameters:
Example:
The functions ovfshalc, ovfshalw, and ovfshall arithmetically shift 1-byte, 2-
byte, and 4-byte data dst to the left by one bit, respectively, 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 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 ovfshalw and ovfshall functions are valid when the CPU is other than
H8/300.
