This documentation is intended for internal Performance Co-Pilot
(PCP) developer use.
These interfaces are not part of the PCP APIs that are guaranteed
to remain fixed across releases, and they may not work, or may
provide different semantics at some point in the future.
__pmParseCtime reverses the asctime(3) function. It accepts a
string specifying a time, and fills in the given tm structure.
string is either a fully specified date and time in the format
Day MMM DD HH:MM:SS YYYY (e.g "Mon Mar 4 13:07:47 1996") or a
partially specified date and time like "1996", "Mar 1996", "Mar 4
1996", "Mar", "13:07:47", "13:07", "Mar 4 13:07:47",.... For a
partially specified date and time, the order of the fields must
be preserved and missing fields are filled in from the current
date and time.
The seconds component (SS) may be a floating point number, for
example the time "13:07:47.5". The 12 hour clock is also
supported, so "13:07" and "1:07 pm" are equivalent.
__pmParseCtime returns 0 if successful. It returns -1 and a
dynamically allocated error message string in errmsg, if the
given string does not parse. Be sure to free(3) the error
message string.
The tm structure returned in rslt should only be used as an
argument to the __pmConvertTime function, as it contains encoded
information that will only be correctly interpreted by
__pmConvertTime.
