Turn text string to URI-encoded XX version At this point, we're converting from ISO-8859-x (8-bit), not UTF8 as in the SIP protocol spec If doreserved == 1 we will convert reserved characters also. RFC 2396, section 2.4 outbuf needs to have more memory allocated than the instring to have room for the expansion. Every char that is converted is replaced by three ASCII characters. | |

Turn text string to URI-encoded XX version At this point, we're converting from ISO-8859-x (8-bit), not UTF8 as in the SIP protocol spec If doreserved == 1 we will convert reserved characters also. RFC 2396, section 2.4 outbuf needs to have more memory allocated than the instring to have room for the expansion. Every char that is converted is replaced by three ASCII characters.

Note: It is very important to use only unsigned variables to hold bit flags, as otherwise you can fall prey to the compiler's sign-extension antics if you try to use the top two bits in your variable. The flag macros below use a set of compiler tricks to verify that the caller is using an "unsigned int" variable to hold the flags, and nothing else. If the caller uses any other type of variable, a warning message similar to this: warning: comparison of distinct pointer types lacks cast will be generated. The "dummy" variable below is used to make these comparisons. Also note that at -O2 or above, this type-safety checking does _not_ produce any additional object code at all.
