.BI "unsigned long bitmap_find_next_zero_area_off(unsigned\ long\ *\ " "map" ", unsigned\ long\ " "size" ", unsigned\ long\ " "start" ", unsigned\ int\ " "nr" ", unsigned\ long\ " "align_mask" ", unsigned\ long\ " "align_offset" ");"
.SH "ARGUMENTS"
.PP
\fImap\fR
.RS 4
The address to base the search on
.RE
.PP
\fIsize\fR
.RS 4
The bitmap size in bits
.RE
.PP
\fIstart\fR
.RS 4
The bitnumber to start searching at
.RE
.PP
\fInr\fR
.RS 4
The number of zeroed bits we\*(Aqre looking for
.RE
.PP
\fIalign_mask\fR
.RS 4
Alignment mask for zero area
.RE
.PP
\fIalign_offset\fR
.RS 4
Alignment offset for zero area\&.
.RE
.SH "DESCRIPTION"
.PP
The
\fIalign_mask\fR
should be one less than a power of 2; the effect is that the bit offset of all zero areas this function finds plus
\fIalign_offset\fR
is multiple of that power of 2\&.
