NAME

rohc_comp_set_mrru − Set the Maximum Reconstructed Reception Unit (MRRU).

SYNOPSIS

#include <rohc/rohc_comp.h>

bool rohc_comp_set_mrru(
struct rohc_comp *const comp,
const size_t mrru
);

DESCRIPTION

Set the Maximum Reconstructed Reception Unit (MRRU).

The MRRU is the largest cumulative length (in bytes) of the ROHC segments that are parts of the same ROHC packet. In short, the ROHC decompressor does not expect to reassemble ROHC segments whose total length is larger than MRRU. So, the ROHC compressor shall not segment ROHC packets greater than the MRRU.

The MRRU value must be in range [0 ; ROHC_MAX_MRRU]. Remember that the MRRU includes the 32−bit CRC that protects it. If set to 0, segmentation is disabled as no segment headers are allowed on the channel. No segment will be generated.

If segmentation is enabled and used by the compressor, the function rohc_comp_get_segment2 can be used to retrieve ROHC segments.

PARAMETERS

	comp		The ROHC compressor
	mrru		The new MRRU value (in bytes)

STRUCTURES

RETURN VALUE

true if the MRRU was successfully set, false otherwise

EXAMPLE

struct rohc_comp *comp;
rru = 500;

/* set the MRRU at compressor */
if(!rohc_comp_set_mrru(comp, mrru))
{
fprintf(stderr, "failed to set the MRRU at compressor0);
goto destroy_comp;
}
