WAITED^IO[X]
WAITED^IO[X] performs a WRITE, READ, or WRITEREAD depending on the values
of writecount and readcount. If writecount is 0 and the file is not a process file, a READ
is done. If readcount is 0 a WRITE is done, otherwise a WRITEREAD is performed.
file input
INT:value
specifies the file number for the operation.
buffer input
is a pointer to the buffer to be transferred.
writecount input
INT:value
specifies the number of bytes to write.
readcount input
INT:value
specifies the number of bytes to read.
countxfered output
is a pointer to the number of bytes transferred. The number of bytes is passed by
AWAITIO[X], which is used to implement this procedure.
