.Sh NAME
|
|
.Nm strptime
|
|
.Nd parse date and time string
|
|
.Sh SYNOPSIS
|
|
.Fd #include <time.h>
|
|
.Ft const char *
|
|
.Fn strptime "const char *buf" "const char *format" "struct tm *timeptr"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn strptime
|
|
function parses the string in the buffer
|
|
.Fa buf
|
|
according to the string pointed to by
|
|
.Fa format ,
|
|
and fills in the elements of the structure pointed to by
|
|
.Fa timeptr .
|
|
Thus, it can be considered the reverse operation of
|
|
.Xr strftime 3 .
|
|
.Pp
|
|
The
|
|
.Fa format
|
|
string consists of zero or more conversion specifications and
|
|
ordinary characters.
|
|
All ordinary characters are matched exactly with the buffer, where
|
|
white space in the format string will match any amount of white space
|
|
in the buffer.
|
|
All conversion specifications are identical to those described in
|
|
.Xr strftime 3 .
|
|
.Sh RETURN VALUES
|
|
Upon successful completion,
|
|
.Fn strptime
|
|
returns the pointer to the first character in
|
|
.Fa buf
|
|
that has not been required to satisfy the specified conversions in
|
|
.Fa format .
|
|
It returns
|
|
.Dv NULL
|
|
if one of the conversions failed.
