NAME

       cgiEscape - HTML escape certain characters in a string

SYNOPSYS

       #include <cgi.h>

       char *cgiEscape (char *string);

DESCRIPTION

       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.

RETURN VALUE

       cgiEscape() returns a pointer to the sanitised string or NULL in case of error.
