char *Ns_DStringAppend( Ns_DString *dsPtr, char *string );
The Ns_DStringAppend macro appends the specified string plus a terminating null character to the end of the Ns_DString. The string may overflow from static space to the heap as a result of calling this function. It returns the string associated with the current Ns_DString.
Ns_DString ds; Ns_DStringInit(&ds); Ns_DStringAppend(&ds, "foo"); /* do something with the dstring */ printf("%s\n", ds.string); Ns_DStringFree(&ds); /* finished with dstring */
The resulting Ns_DString,
ds, would contain "foo\0" and have a length of 3.
