problem, we have come up with a solution: QA only verifies one package (that is, the parent Package). If this package passes verification, we generate packages from other channels through the parent package, in this way, QA does not need to identify so many channel packages, and the risks are effectively controlled.Maybe you will ask: is it feasible to generate other packages with one package ??The reason is: because each channel only has a channel number change, and other content does not chan
SyntaxCompress [-dfvcV] [-B maxbits] [file...]Parameters: C output result to standard output device (usually screen) F. Write the file forcibly. If the target file already exists, it will be overwritten (force) V prints program execution messages on the screen (verbose) B sets the upper limit of the number of common strings. It is calculated in bits and can be set to 9 to 16 bits. Because the larger the value, the more common strings can be used and the larger the compression ratio,
] [-B maxbits] [file...]
Note:Compress is a fairly old unix file compression command. after compression, A. Z extension file name will be added to the compressed file to distinguish uncompressed files. the compressed file can be decompressed with uncompress. To compress several files into one compressed file, you must first tar the file and then compress it. Since gzip can produce a better compression ratio, most people have switched to gzip as the archive compression tool.

the usage of the file function.
The first form parameter in the fopen () function represents the file name, which can contain two parts: path and file name. For example:
"B: test. dat"
"C:/TC/test. dat"
Note that writing the path "C:/TC/test. dat" is incorrect.
The second form parameter indicates the type of the file to open. For more information about file type

Test. OK is also a general asserted. You can also use node-inspector to debug the unit test program of NodeUnit.

value. ASCII characters used to form packets are hexadecimal characters. Although the characters used in the ASCII mode are twice that in the RTU mode, it is easier to translate and process the ASCII data. In addition, the characters in the RTU mode must be transmitted as continuous data streams, in ASCII mode, characters can be separated by 1 s to adapt to faster machines.
