blkqread(3G) blkqread(3G)
NAME
blkqread - reads multiple entries from the queue
C SPECIFICATION
long blkqread(data, n)
short *data
short n;
PARAMETERS
data expects a pointer to the buffer that is to receive the queue
information.
n expects the number of elements in the buffer.
FUNCTION RETURN VALUE
The returned value of the function is the number of 16 bit words of data
actually read into the data buffer. Note that this number will be twice
the number of complete queue entries read, because each queue entry
consists of two 16 bit words.
DESCRIPTION
blkqread reads multiple entries from the input queue and stores them in
the array pointed to by data. This function fills the data buffer with
paired values (a device number and the value of that device).
