Description
The BINCREATE() function creates a new binary file. The <expC> is the name of the file to be created. BINCREATE() leaves the created file open, and returns a file descriptor when successful, or a -1 if an error occurs. Since the file descriptor is used to identify an open binary file, always assign the BINCREATE() return value to a memory variable.
Example
fd = bincreate("file.obj") count = binread(fd, 4) count = bin2l(count) count = l2bin(count + 1) binseek(fd, 512, 0) binwrite(fd, count) binclose(fd)
