[Linphone-developers] [PATCH] fix warning in linphonecore.c on amd64

[Chi-Thanh Christopher Nguyen]

Hi,

on amd64, size_t is a 64 bit unsigned int. Thus, the compiler will
generate a warning in the following line of linphonecore.c, because %i
is a 32 bit signed int:

               snprintf(clen,sizeof(clen),"%i",strlen(dtmf_body));

The attached patch changes "%i" to "%zu" and will allow compilation with
-Werror on amd64. Note that the z modifier was introduced in C99, so it
may not be portable regarding older compilers. Ymmv.


Best regards,
Chi-Thanh Christopher Nguyen
