NAME¶
glDeleteSync - delete a sync object
C SPECIFICATION¶
void
glDeleteSync(GLsync sync);
PARAMETERS¶
sync
The sync object to be deleted.
DESCRIPTION¶
glDeleteSync deletes the sync object specified by
sync. If the
fence command corresponding to the specified sync object has completed, or if
no
glWaitSync() or
glClientWaitSync() commands are blocking on
sync, the object is deleted immediately. Otherwise,
sync is
flagged for deletion and will be deleted when it is no longer associated with
any fence command and is no longer blocking any
glWaitSync() or
glClientWaitSync() command. In either case, after
glDeleteSync
returns, the name
sync is invalid and can no longer be used to refer to
the sync object.
glDeleteSync will silently ignore a
sync value of zero.
NOTES¶
glSync is only supported if the GL version is 3.2 or greater, or if the
ARB_sync extension is supported.
ERRORS¶
GL_INVALID_VALUE is generated if
sync is neither zero or the name
of a sync object.
