errno — 标准 errno 系统符号 ¶

此模块使可用标准 errno 系统符号。每个符号的值是相应整数值。名称和描述借用自 linux/include/errno.h , which should be all-inclusive.

errno. errorcode ¶

Dictionary providing a mapping from the errno value to the string name in the underlying system. For instance, errno.errorcode[errno.EPERM] 映射到 'EPERM' .

To translate a numeric error code to an error message, use os.strerror() .

Of the following list, symbols that are not used on the current platform are not defined by the module. The specific list of defined symbols is available as errno.errorcode.keys() . Symbols available can include:

errno. EPERM ¶
