我想知道REDIS如何写入二进制数据。 它打开一个不是“b”模式的文件。
fp = fopen(tmpfile,"w")
在这方面的任何帮助。
最佳答案
在liunx中，fopen没有b模式，参见fopen man doc:
r Open text file for reading. The stream is positioned at the beginning of the file.
r+ Open for reading and writing. The stream is positioned at the beginning of the file.
w Truncate file to zero length or create text file for writing. The stream is positioned at the beginning of the file.
w+ Open for reading and writing. The file is created if it does not exist, otherwise it is truncated. The stream is positioned at the beginning of the file.
a Open for appending (writing at end of file). The file is created if it does not exist. The stream is positioned at the end of the file.
a+ Open for reading and appending (writing at end of file). The file is created if it does not exist. The initial file position for reading is at the beginning of the file,
but output is always appended to the end of the file.
