Описание (Description)
pmParseInterval
parses the argument string specifying an interval
of time and fills in the tv_sec
and tv_usec
components of the
rslt structure to represent that interval.
The input string is most commonly the argument following a -t
command line option to a PCP application, and the syntax is fully
described in PCPIntro(1).
Диагностика (Diagnostic)
pmParseInterval
returns 0 and errmsg is undefined if the parsing
is successful.
If the given string does not conform to the required syntax
pmParseInterval
returns -1 and a dynamically allocated error
message string in errmsg. The error message is terminated with a
newline and includes the text of the input string along with an
indicator of the position at which the error was detected, e.g.
4minutes 30mumble
^ -- unexpected value
In the case of an error, the caller is responsible for calling
free(3) to release the space allocated for errmsg.
