Source code...
Code:
main() {
//char *querystring;
int querylen;
char *line;
FILE *fp;
FILE *fp2;
if ( getenv("CONTENT_LENGTH") != NULL ) {
querylen=atoi(getenv("CONTENT_LENGTH"));
line=malloc(querylen*512);
//querystring=malloc(querylen*512);
} else {
querylen=10240;
line=malloc(querylen*512);
//querystring=malloc(querylen*512);
}
char querystring[querylen];
fread ( querystring, querylen, 1, stdin );
printf("Content-type: text/plain\n\n");
fp=fopen("/opt/moneylikes/tmp/file", "wb+");
fwrite(querystring, querylen, 1, fp);
exit(0);
}
I want to say thanks in advanced to anyone who can help me fill in the missing info..
I am pretty sure it is how i handle the headder info with the CGI.. i am just not sure what exactly it is i am doing wrong..
