The user can add a callback function to the list, along with user data. When the callback is invoked, it is passed this user data, along with \&callback data specified by the invoking routine. The type of this callback data is determined by the invoking routine. .SH METHODS .ta 20m .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbSoCallbackList\*(Cr() .br .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(Cb~SoCallbackList\*(Cr() .br .in 1i \f1Constructor and destructor. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Crvoid .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbaddCallback\*(Cr(SoCallbackListCB *f, void *userData = NULL) .br .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Crvoid .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbremoveCallback\*(Cr(SoCallbackListCB *f, void *userData = NULL) .br .in 1i \f1Adds a function to or removes a function from the list of callback functions. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Crvoid .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbclearCallbacks\*(Cr() .br .in 1i \f1Clears all callback functions from the list. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Crint .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbgetNumCallbacks\*(Cr() const .br .in 1i \f1Returns the number of callback functions in the list. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Crvoid .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbinvokeCallbacks\*(Cr(void *callbackData) .br .in 1i \f1Invokes each callback function in the list, passing each function the user data supplied when they were registered here, and \*(CrcallbackData\f1, the callback-specific data supplied by the caller. .sp .in 0.5i
