nbytes,
int
buffer);

ARGUMENTS
buffer Specifies the buffer in which you want to store the bytes
or from which you want the stored data returned.
bytes Specifies the bytes, which are not necessarily ASCII or
null-terminated.
display Specifies the connection to the X server.
nbytes Specifies the number of bytes to be stored.
nbytes_return Returns the number of bytes in the buffer.
rotate Specifies how much to rotate the cut buffers.
DESCRIPTION
The data can have embedded null characters and need not be null-
terminated. The cut buffer's contents can be retrieved later by any
client calling
XFetchBytes.
XStoreBytes can generate a
BadAlloc error.
If an invalid buffer is specified, the call has no effect. The data
can have embedded null characters and need not be null-terminated.
XStoreBuffer can generate a
BadAlloc error.
The
XFetchBytes function returns the number of bytes in the
nbytes_return argument, if the buffer contains data. Otherwise, the
function returns NULL and sets nbytes to 0. The appropriate amount
of storage is allocated and the pointer returned. The client must
free this storage when finished with it by calling
XFree.
The
XFetchBuffer function returns zero to the nbytes_return argument
if there is no data in the buffer or if an invalid buffer is
specified.
XFetchBuffer can generate a
BadValue error.
The
XRotateBuffers function rotates the cut buffers, such that buffer
0 becomes buffer n, buffer 1 becomes n + 1 mod 8, and so on. This
cut buffer numbering is global to the display. Note that
XRotateBuffers generates
BadMatch errors if any of the eight buffers
have not been created.
XRotateBuffers can generate a
BadMatch error.
DIAGNOSTICS
BadAlloc The server failed to allocate the requested resource or
server memory.
BadAtom A value for an Atom argument does not name a defined Atom.
BadMatch Some argument or pair of arguments has the correct type and
range but fails to match in some other way required by the
request.
BadValue Some numeric value falls outside the range of values
accepted by the request. Unless a specific range is
specified for an argument, the full range defined by the
argument's type is accepted. Any argument defined as a set
of alternatives can generate this error.
