# Go references to C

Within the Go file, C's struct field names that are keywords in Go
can be accessed by prefixing them with an underscore: if x points at a C
struct with a field named "type", x._type accesses the field.
C struct fields that cannot be expressed in Go, such as bit fields
or misaligned data, are omitted in the Go struct, replaced by
appropriate padding to reach the next field or the end of the struct.

		} else {

A note about ZIP64:

To be backwards compatible the FileHeader has both 32 and 64 bit Size
fields. The 64 bit fields will always contain the correct value and
for normal archives both fields will be the same. For files requiring
the ZIP64 format the 32 bit fields will be 0xffffffff and the 64 bit
fields must be used instead.

as <code>reader_buf</code> and <code>reader_r</code>.
Hence, if register <code>R1</code> contains a pointer to
a <code>reader</code>, assembly can reference the <code>r</code> field
as <code>reader_r(R1)</code>.

a struct with a <code>_size</code> field), <code>#include
