cgiEscape - HTML escape certain characters in a string
#include <cgi.h> char *cgiEscape (char *string);
This function returns a pointer to a sanitised string. It converts <, & and > into HTML entities so that the result can be displayed without any danger of cross-site scripting in a browser. The result may be passed to free(3) after use. This routine is meant to be called before any user provided strings are returned to the browser.
cgiEscape() returns a pointer to the sanitised string or NULL in case of error.
