mas_put(3mas)


mas_put -- write metrics and metric registration information for provider use

Synopsis

   cc [options] file -lmas
   

#include <mas.h> int mas_put(void);

Description

The function mas_put writes metric registration information to the metric registration file(s). The file name(s) and permissions are those that were previously passed to mas_init during MAS provider initialization. The first time mas_put is called, it creates the metric registration file(s). On subsequent invocations the metric registration files are rewritten with the updated registration information.

If a provider is using an internal metric segment within the metric registration header file, or if dynamic registration was not requested by calling mas_init with file names for the metric registration table, metadata, and strings table, then mas_put should not be called more than once.

Return values

On success, mas_put returns 0.

On failure, mas_put returns -1 and sets mas_errno to identify the error.

Future directions

Currently, mas_put does not notify active consumers that a change in registration information has occurred. This may be supported in a future release.
