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
pmParseInterval returns 0 and errmsg is undefined if the parsing is
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.
