warning: implicit declaration of function ‘strptime’<br>
<br>
I'm trying to do some basic Date parsing in Varnish. But I get this<br>
warning on compile.<br>
<br>
Here's the relevant bits of VCL:<br>
<br>
C{<br>
#include <time.h><br>
#include <sys/time.h><br>
#include <stdio.h><br>
#include <stdlib.h><br>
}C<br>
<br>
sub date_skew {<br>
C{<br>
time_t t = time(NULL);<br>
time_t digestepoch;<br>
struct tm tm;<br>
char *digestdate = VRT_GetHdr(sp, HDR_REQ, "\021x-digestdate:");<br>
if (!strptime(digestdate, "%a, %d %b %Y %H:%M:%S GMT", &tm)) {<br>
VRT_SetHdr(sp, HDR_REQ, "\010dateparsefail:",<br>
"1\0", vrt_magic_string_end);<br>
} else {<br>
digestepoch = mktime(&tm);<br>
if (abs(digestepoch - t) > 7200) {<br>
VRT_SetHdr(sp, HDR_REQ,<br>
"\010dateskewfail:", "1\0", vrt_magic_string_end);<br>
}<br>
}<br>
}C<br>
}<br>
<br>
Note: Later on, I'll call error if either of the two headers above are set.<br>
<br>
I've discovered that if I add:<br>
<br>
#define _XOPEN_SOURCE 500<br>
<br>
to the first C{ }C block, it passes muster. Any clue why? (may not be<br>
varnish related).<br>
<br>
Varnish related: will that impact anything else inside varnish?<br>
