195 Set the underlying allocation strategy. The \fBbest\fR fit strategy tells |
|
196 libumem to use the smallest free segment possible. The \fBinstant\fR fit |
|
197 strategy approximates the best fit strategy in constant cpu time. The |
|
198 \fBfirst\fR fit strategy takes the first free segment that can honor the |
|
199 allocation. The \fBnext\fR fit strategy uses the next free segment after the |
|
200 previously allocated one. |
