.SH DESCRIPTION
.LP
The \fBelf32_checksum()\fR function returns a simple checksum of selected
sections of the image identified by \fIelf\fR. The value is typically used as
the \fB\&.dynamic\fR tag \fBDT_CHECKSUM\fR, recorded in dynamic executables and
shared objects.
.sp
.LP
Selected sections of the image are used to calculate the checksum in order that
its value is not affected by utilities such as \fBstrip\fR(1).
.sp
.LP
For the 64\(mibit class, replace 32 with 64 as appropriate.
