PMPARSEINTERVAL(3) Library Functions Manual PMPARSEINTERVAL(3)
pmParseInterval, pmParseHighResInterval - convert interval string
to binary time structure
#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
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 com‐
mand line option to a PCP application, and the syntax is fully de‐
scribed 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 pmPar‐
seInterval 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.
