PMPARSEINTERVAL(3)      Library Functions Manual      PMPARSEINTERVAL(3)

NAME

       pmParseInterval, pmParseHighResInterval - convert interval string
       to binary time structure

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmParseInterval(const char *string, struct timeval *urslt,
               char **errmsg);
       int pmParseHighResInterval(const char *string, struct timespec
               *nrslt, 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
       urslt structure to represent that  interval  (microsecond  preci‐
       sion).

       Similarly,  pmParseHighResInterval parses the argument string and
       fills in the tv_sec and tv_nsec components of the nrslt structure
       to represent that interval (nanosecond precision).

       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).

DIAGNOSTICS

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

       If the given string does not conform to the required  syntax  pm‐
       ParseInterval  returns  -1 and a dynamically allocated error mes‐
       sage 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.
