SE_CompareSingleValues
(
constSE_Single_Value *a_ptr,1
constSE_Single_Value *b_ptr2
);

Definition

When comparing:

integers, floats: normal mathematical rules apply

EEs: underlying compare functions for those codes apply

boolean to boolean: FALSE is less than TRUE

string to string: strcmp() rules apply

boolean to anything but a boolean: FALSE is 0, TRUE is 1, and a numeric comparison is used

string to anything but a string: the string is 0, and a numeric comparison is used


Returns

-1 if a_ptr is NULL and b_ptr is non-NULL, or *a_ptr < *b_ptr
0 if both arguments are NULL, or *a_ptr == *b_ptr
1 if b_ptr is NULL and a_ptr is non-NULL, or *a_ptr > *b_ptr

Parameters Notes

1 pointer to 1st SE_Single_Value to be compared

2 pointer to 2nd SE_Single_Value to be compared
