.SH "DESCRIPTION"
.PP

\fBglFlushMappedBufferRange\fR
indicates that modifications have been made to a range of a mapped buffer\&. The buffer must previously have been mapped with the
\fBGL_MAP_FLUSH_EXPLICIT\fR
flag\&.
\fIoffset\fR
and
\fIlength\fR
indicate the modified subrange of the mapping, in basic units\&. The specified subrange to flush is relative to the start of the currently mapped range of the buffer\&.
\fBglFlushMappedBufferRange\fR
may be called multiple times to indicate distinct subranges of the mapping which require flushing\&.
.SH "ERRORS"
.PP

\fBGL_INVALID_VALUE\fR
is generated if
\fIoffset\fR
or
\fIlength\fR
is negative, or if
\fIoffset\fR
+
\fIlength\fR
exceeds the size of the mapping\&.
.PP

\fBGL_INVALID_OPERATION\fR
is generated if zero is bound to
\fItarget\fR\&.
.PP

\fBGL_INVALID_OPERATION\fR
is generated if the buffer bound to
\fItarget\fR
is not mapped, or is mapped without the
\fBGL_MAP_FLUSH_EXPLICIT\fR
flag\&.
