* Name: setbuffer()
|
||
|
|
*
|
||
|
|
* Description:
|
||
|
|
* The setbuffer() function is a wrapper around setvbuf() which
|
||
|
|
* enables full buffering on a buffer allocated by the caller, assuming
|
||
|
|
* buffer is not a null pointer.
|
||
|
|
*
|
||
|
|
* Input Parameters:
|
||
|
|
* stream - the stream to flush
|
||
|
|
* buffer - The user allocated buffer to use.
|
||
|
|
* If NULL, buffering is disabled.
|
||
|
|
* size - size of the user buffer.
