41 | (description | |
42 | "libdaemon is a lightweight C library that eases the writing of UNIX | |
43 | daemons. It consists of the following parts: | |
44 | ||
45 | • A wrapper around fork() which does the correct daemonization procedure of | |
46 | a process | |
47 | ||
48 | • A wrapper around syslog() for simpler and compatible log output to Syslog | |
49 | or STDERR | |
50 | ||
51 | • An API for writing PID files | |
52 | ||
53 | • An API for serializing UNIX signals into a pipe for usage with select() or | |
54 | poll() | |
55 | ||
56 | • An API for running subprocesses with STDOUT and STDERR redirected to | |
57 | syslog. | |
58 | ||
59 | APIs like these are used in most daemon software available. It is not that | |
60 | simple to get it done right and code duplication is not a goal.") | |
