C SYNOPSIS

11       int pmParseInterval(const char *string, struct timeval *rslt,
12               char **errmsg);

DESCRIPTION

17       pmParseInterval parses the argument string specifying  an  interval  of
18       time  and fills in the tv_sec and tv_usec components of the rslt struc‐
19       ture to represent that interval.
20
21       The input string is most commonly the argument following a  -t  command
22       line  option to a PCP application, and the syntax is fully described in
23       PCPIntro(1).
24
25       pmParseInterval returns 0 and errmsg is undefined  if  the  parsing  is
26       successful.
27
28       If  the given string does not conform to the required syntax pmParseIn‐
29       terval returns -1 and a dynamically allocated error message  string  in
30       errmsg.   The  error  message is terminated with a newline and includes
31       the text of the input string along with an indicator of the position at
32       which the error was detected, e.g.
33                 4minutes 30mumble
34                            ^ -- unexpected value
35
36       In  the case of an error, the caller is responsible for calling free(3)
37       to release the space allocated for errmsg.
