XStoreBytes(3) XLIB FUNCTIONS XStoreBytes(3)NAME
XStoreBytes, XStoreBuffer, XFetchBytes, XFetchBuffer, XRotateBuffers-
manipulate cut and paste buffers
int XStoreBytes(Display *display, char *bytes, int nbytes);
int XStoreBuffer(Display *display, char *bytes, int nbytes, int buf‐
char *XFetchBytes(Display *display, int *nbytes_return);
char *XFetchBuffer(Display *display, int *nbytes_return, int buffer);
int XRotateBuffers(Display *display, int rotate);
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-
display Specifies the connection to the X server.
nbytes Specifies the number of bytes to be stored.
Returns the number of bytes in the buffer.
rotate Specifies how much to rotate the cut buffers.
The data can have embedded null characters and need not be null-termi‐
nated. The cut buffer's contents can be retrieved later by any client
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
XRotateBuffers can generate a BadMatch error.
BadAlloc The server failed to allocate the requested resource or
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
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.
