writeBytes
Syntax
writeBytes(handle, bytes)
Details
Write the entire buffer to the file. The buffer must be a char scalar or char vector. If the operation succeeds, it returns the actual number of bytes written; otherwise, an IOException will be raised.
Examples
// define a file copy function
def fileCopy(source, target){
s = file(source)
len = s.seek(0,TAIL)
s.seek(0,HEAD)
t = file(target,"w")
if(len==0) return
do{
buf = s.readBytes(min(len,1024))
t.writeBytes(buf)
len -= buf.size()
}while(len)
};
fileCopy("test.txt","testcopy.txt");
