void ast_register_file_version | ( | const char * | file, |

Register the version of a source code file with the core.
file | the source file name |
version | the version string (typically a SVN revision keyword string) |
This function should not be called directly, but instead the ASTERISK_FILE_VERSION macro should be used to register a file with the core.

void ast_replace_sigchld | ( | void | ) |
Replace the SIGCHLD handler.
Normally, Asterisk has a SIGCHLD handler that is cleaning up all zombie processes from forking elsewhere in Asterisk. However, if you want to wait*() on the process to retrieve information about it's exit status, then this signal handler needs to be temporarily replaced.
Code that executes this function *must* call ast_unreplace_sigchld() after it is finished doing the wait*().
