It takes three optional function pointers which +are called when the parent structure (in this case an \s-1RSA\s0 structure) is +initially created, when it is copied and when it is freed up. If any or all of +these function pointer arguments are not used they should be set to \s-1NULL\s0. The +precise manner in which these function pointers are called is described in more +detail below. \fB\f(BIRSA_get_ex_new_index()\fB\fR also takes additional long and pointer +parameters which will be passed to the supplied functions but which otherwise +have no special meaning. It returns an \fBindex\fR which should be stored +(typically in a static variable) and passed used in the \fBidx\fR parameter in +the remaining functions. Each successful call to \fB\f(BIRSA_get_ex_new_index()\fB\fR +will return an index greater than any previously returned, this is important +because the optional functions are called in order of increasing index value. +.PP +\&\fB\f(BIRSA_set_ex_data()\fB\fR is used to set application specific data, the data is +supplied in the \fBarg\fR parameter and its precise meaning is up to the +application. +.PP +\&\fB\f(BIRSA_get_ex_data()\fB\fR is used to retrieve application specific data. The data +is returned to the application, this will be the same value as supplied to +a previous \fB\f(BIRSA_set_ex_data()\fB\fR call. +.PP +\&\fB\f(BInew_func()\fB\fR is called when a structure is initially allocated (for example +with \fB\f(BIRSA_new()\fB\fR. The parent structure members will not have any meaningful +values at this point. This function will typically be used to allocate any +application specific structure. +.PP +\&\fB\f(BIfree_func()\fB\fR is called when a structure is being freed up. The dynamic parent +structure members should not be accessed because they will be freed up when +this function is called. +.PP +\&\fB\f(BInew_func()\fB\fR and \fB\f(BIfree_func()\fB\fR take the same parameters. \fBparent\fR is a +pointer to the parent \s-1RSA\s0 structure. \fBptr\fR is a the application specific data +(this wont be of much use in \fB\f(BInew_func()\fB\fR. \fBad\fR is a pointer to the +\&\fB\s-1CRYPTO_EX_DATA\s0\fR structure from the parent \s-1RSA\s0 structure: the functions +\&\fB\f(BICRYPTO_get_ex_data()\fB\fR and \fB\f(BICRYPTO_set_ex_data()\fB\fR can be called to manipulate +it. The \fBidx\fR parameter is the index: this will be the same value returned by +\&\fB\f(BIRSA_get_ex_new_index()\fB\fR when the functions were initially registered. Finally +the \fBargl\fR and \fBargp\fR parameters are the values originally passed to the same +corresponding parameters when \fB\f(BIRSA_get_ex_new_index()\fB\fR was called. +.PP +\&\fB\f(BIdup_func()\fB\fR is called when a structure is being copied. Pointers to the +destination and source \fB\s-1CRYPTO_EX_DATA\s0\fR structures are passed in the \fBto\fR and +\&\fBfrom\fR parameters respectively. The \fBfrom_d\fR parameter is passed a pointer to +the source application data when the function is called, when the function returns +the value is copied to the destination: the application can thus modify the data +pointed to by \fBfrom_d\fR and have different values in the source and destination. +The \fBidx\fR, \fBargl\fR and \fBargp\fR parameters are the same as those in \fB\f(BInew_func()\fB\fR +and \fB\f(BIfree_func()\fB\fR. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fB\f(BIRSA_get_ex_new_index()\fB\fR returns a new index or \-1 on failure (note 0 is a valid +index value). +.PP +\&\fB\f(BIRSA_set_ex_data()\fB\fR returns 1 on success or 0 on failure. +.PP +\&\fB\f(BIRSA_get_ex_data()\fB\fR returns the application data or 0 on failure. 0 may also +be valid application data but currently it can only fail if given an invalid \fBidx\fR +parameter. +.PP +\&\fB\f(BInew_func()\fB\fR and \fB\f(BIdup_func()\fB\fR should return 0 for failure and 1 for success. +.PP +On failure an error code can be obtained from ERR_get_error(3). +.SH "BUGS" +.IX Header "BUGS" +\&\fB\f(BIdup_func()\fB\fR is currently never called. +.PP +The return value of \fB\f(BInew_func()\fB\fR is ignored. +.PP +The \fB\f(BInew_func()\fB\fR function isn't very useful because no meaningful values are +present in the parent \s-1RSA\s0 structure when it is called. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +rsa(3), CRYPTO_set_ex_data(3) +.SH "HISTORY" +.IX Header "HISTORY" +\&\fIRSA_get_ex_new_index()\fR, \fIRSA_set_ex_data()\fR and \fIRSA_get_ex_data()\fR are +available since SSLeay 0.9.0. |
