Andrei,
thanks very much! I have now taken Jiri's advice and use the textops
package to add the header.
However, in the package, I'm calling append_hf with the message and a
char* which is the new header. From the look of it, it seems that
append_hf should call str_fixup for the char*.
append_hf is ment to be called from the script. When the script is
processed str_fixup will be automatically called (and it will convert
char* to str*).
*_fixup functions area a way of pre-processing parameters on ser
initialization (in this case instead of computing strlen(str) each
time append_hf is called from the script, it will be computed only once
on ser startup; another example is using it to compile the regular
expressions only once , see search & fixup_regex).
If you call append_hf directly (not from the script) make sure it will
receive str parameters. It expects str* parameters although is declared
with char*.
E.g.:
str str1;
str1.s=your_string; str1.len=strlen(your_string);
append_hf(msg, (char*) &str1, 0);
append_hf has char* parameters because this is the prototype for module
exported function:
typedef int (*cmd_function)(struct sip_msg*, char*, char*);
