11 const char * idn2_check_version(const char * req_version);
12
14 const char * req_version
15 version string to compare with, or NULL.
16
18 Check IDN2 library version. This function can also be used to read out
19 the version of the library code used. See IDN2_VERSION for a suitable
20 req_version string, it corresponds to the idn2.h header file version.
21 Normally these two version numbers match, but if you are using an
22 application built against an older libidn2 with a newer libidn2 shared
23 library they will be different.
24
25 Return value: Check that the version of the library is at minimum the
26 one given as a string in req_version and return the actual version
27 string of the library; return NULL if the condition is not met. If
28 NULL is passed to this function no check is done and only the version
29 string is returned.
