* NAME
|
||
|
|
* databingen - fill a buffer with a data pattern
|
||
|
|
*
|
||
|
|
* SYNOPSIS
|
||
|
|
* (void) databingen(mode, buffer, bsize, offset)
|
||
|
|
* int mode;
|
||
|
|
* char *buffer;
|
||
|
|
* int bsize;
|
||
|
|
* int offset;
|
||
|
|
*
|
||
|
|
* DESCRIPTION
|
||
|
|
* datagen fills the buffer pointed to by 'buffer' with 'bsize' bytes
|
||
|
|
* of data of the form indicated by 'mode'.
|
||
|
|
* All modes (expect r -random) are file offset based.
|
||
|
|
* This allows more than process to do writing to the file without
|
||
|
|
* corrupting it if the same modes were used.
|
||
|
|
* They data modes to choose from, these are:
|
||
|
|
*
|
||
|
|
* 'a' - writes an alternating bit pattern (i.e. 0x5555555...)
|
||
|
|
*
|
||
|
|
* 'c' - writes a checkerboard pattern (i.e. 0xff00ff00ff00...)
|
||
|
|
*
|
||
|
|
* 'C' - writes counting pattern (i.e. 0 - 07, 0 - 07, ...);
|
||
|
|
*
|
||
|
|
* 'o' - writes all bits set (i.e. 0xffffffffffffff...)
|
||
|
|
*
|
||
|
|
* 'z' - writes all bits cleared (i.e. 0x000000000...);
|
||
|
|
*
|
||
|
|
* 'r' - writes random integers
|
||
|
|
*
|
||
|
|
* RETURN VALUE
|
||
|
|
* None
|
||
|
|
*
