KHTTP_FCGI_GETFD(3) Library Functions Manual KHTTP_FCGI_GETFD(3) NAME khttp_fcgi_getfd -- get the FastCGI control socket LIBRARY library "libkcgi" SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> int khttp_fcgi_getfd(const struct kfcgi *fcgi); DESCRIPTION Get the control socket used for handling FastCGI processes. This should only be used for polling purposes in asynchronous applications. If the returned socket descriptor is manipulated in any other way, the results are undefined. The returned descriptor is only valid after khttp_fcgi_init(3) and prior to khttp_fcgi_free(3). EXAMPLES The following example starts an application in FastCGI or regular CGI mode depending upon the environment. int main(void) { struct pollfd pfd; struct kreq req; struct kfcgi *fcgi; enum kcgi_err er; int rc; er = khttp_fcgi_init(&fcgi, NULL, 0, NULL, 0, 0); if (er != KCGI_OK) errx(1, "khttp_fcgi_init: %s", kcgi_strerror(er)); pfd.events = POLLIN; pfd.fd = khttp_fcgi_getfd(fcgi); /* Poll on other sockets here... */ while ((rc = poll(&pfd, 1, INFTIM)) != -1) { er = khttp_fcgi_parse(fcgi, &req); if (er != KCGI_OK) err(1, "khttp_fcgi_parse: %s", kcgi_strerror(er)); if (KCGI_EXIT == er) { khttp_free(&req); break; } /* Do something. */ khttp_free(&req); } khttp_fcgi_free(fcgi); if (rc == -1) err(1, "poll"); return 0; } SEE ALSO kcgi(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
