idn2_check_version(3) libidn2 idn2_check_version(3)
NAME
idn2_check_version - API function
SYNOPSIS
#include <idn2.h>
const char * idn2_check_version(const char * req_version);
ARGUMENTS
const char * req_version
version string to compare with, or NULL.
DESCRIPTION
Check IDN2 library version. This function can also be used to read out
the version of the library code used. See IDN2_VERSION for a suitable
req_version string, it corresponds to the idn2.h header file version.
Normally these two version numbers match, but if you are using an ap-
plication built against an older libidn2 with a newer libidn2 shared
library they will be different.
Return value: Check that the version of the library is at minimum the
one given as a string in req_version and return the actual version
string of the library; return NULL if the condition is not met. If
NULL is passed to this function no check is done and only the version
string is returned.
