Module: sip-router Branch: master Commit: 7c7704130af7a25d3301376cc08b1eaa670d0e77 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=7c77041… Author: Jan Janak &lt;jan(a)iptel.org&gt; Committer: Jan Janak &lt;jan(a)iptel.org&gt; Date: Sun Mar 15 20:45:53 2009 +0100 Kamailio compatibility: script flags This patch adds support for script flags identical to those present in the kamailio core. Script flags is a global set of flags which preserve their value for the duration of script processing. Script flags are kept in a global variable in the sip-router core. There are several functions that can be used to manipulate the value of script flags: * setflagsval - This function sets the value of _all_ script flags at once. The new value of all the flags must be combined in the single function parameter. * setsflag - This function sets one particular script flag to 1. The function gets the index of the flag (counting from 0) as a parameter. * resetsflag - This function sets one particular script flag to 0. The function gets the index of the flag (counting from 0) as a parameter. * issflagset - Test the value of a script flag. Returns 1 if the flag is set and -1 otherwise. * getsflags - Returns the value of all script flags combined into a single variable of type flag_t. This function can be used to make a backup copy of script flags. --- flags.c | 37 +++++++++++++++++++++++++++++++++++++ flags.h | 20 ++++++++++++++++++++ 2 files changed, 57 insertions(+), 0 deletions(-) diff --git a/flags.c b/flags.c index e9f559e..70c3333 100644 --- a/flags.c +++ b/flags.c @@ -43,6 +43,10 @@ #include "clist.h" #include "mem/mem.h" +/* Script flags */ +static flag_t sflags = 0; + + int setflag( struct sip_msg* msg, flag_t flag ) { msg->flags |= 1 << flag; return 1; @@ -72,6 +76,39 @@ int flag_in_range( flag_t flag ) { } +int setsflagsval(flag_t val) +{ + sflags = val; + return 1; +} + + +int setsflag(flag_t flag) +{ + sflags |= 1 << flag; + return 1; +} + + +int resetsflag(flag_t flag) +{ + sflags &= ~ (1 << flag); + return 1; +} + + +int issflagset(flag_t flag) +{ + return (sflags & (1<<flag)) ? 1 : -1; +} + + +flag_t getsflags(void) +{ + return sflags; +} + + /* use 2^k */ #define FLAGS_NAME_HASH_ENTRIES 32 diff --git a/flags.h b/flags.h index 62b3235..30809fe 100644 --- a/flags.h +++ b/flags.h @@ -43,6 +43,26 @@ int setflag( struct sip_msg* msg, flag_t flag ); int resetflag( struct sip_msg* msg, flag_t flag ); int isflagset( struct sip_msg* msg, flag_t flag ); + +/* Script flag functions.
