PMPARSEINTERVAL(3) Library Functions Manual PMPARSEINTERVAL(3)
NAME
pmParseInterval - convert interval string to timeval structure
C SYNOPSIS
#include <pcp/pmapi.h>
int pmParseInterval(const char *string, struct timeval *rslt, char **errmsg);
cc ... -lpcp
DESCRIPTION
pmParseInterval parses the argument string specifying an interval of time and fills in the tv_sec and tv_usec components of the rslt struc-
ture 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).
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(3C) to release the space allocated for errmsg.
