WMMEGA FW >= 2.1179
Write data from an indexed array in binary form (packed) to a file.
====Description====
int
fwrite_pack (
int
$handle,
indexed array
$array
,
int
$length
)
This function performs a binary-safe write of array data. The data type is determined by the indexed array definition and can be: BYTE, SHORT, INT or FLOAT. This is an efficient way to write multiple binary bytes to a file in one go.
====Parameters====
$handle: Valid handle of a previously opened file
$data: The indexed array data to be written.
$length: Number of elements to write (this will be multiplied by the array element size in byte which could be 1,2 or 4 depending on the data type)
====Return Values====
Integer **number of bytes successfully written**
====Examples====
$fh = fopen("/fwrite_test.txt","w");
if (!$fh) {
print("File open failed");
} else {
$arr=indexed_array(4,10); // create array of 10 floats
for ($i=0;$i
