An abstract bitmap.

Public Methods

zx_status_t Find (bool is_set, T bitoff, T bitmax, T run_len, T * out)

Sets |out| with the start of the run, or |bitmax| if it is

not found in the provided range.

If the run is not found, "ZX_ERR_NO_RESOURCES" is returned.

bool Get (T bitoff, T bitmax, T * first_unset)

Returns true if all the bits in [*bitoff*, *bitmax*) are set. Afterwards,

*first_unset* will be set to the lesser of bitmax and the index of the

first unset bit after *bitoff*.

bool GetOne (T bitoff)

Returns true in the bit at bitoff is set.

bool Get (T bitoff, T bitmax)

Defined at line 32 of file ../../zircon/system/ulib/bitmap/include/bitmap/bitmap.h

zx_status_t Set (T bitoff, T bitmax)

Sets all bits in the range [*bitoff*, *bitmax*). Only fails on

allocation error or if bitmax

bitoff.

zx_status_t Clear (T bitoff, T bitmax)

Clears all bits in the range [*bitoff*, *bitmax*). Only fails on

allocation error or if bitmax

bitoff.

void ClearAll ()

Clear all bits in the bitmap.

zx_status_t SetOne (T bitoff)

Sets the bit at bitoff. Only fails on allocation error.

Defined at line 35 of file ../../zircon/system/ulib/bitmap/include/bitmap/bitmap.h

zx_status_t ClearOne (T bitoff)

Clears the bit at bitoff. Only fails on allocation error.
