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 application
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.
SEE ALSO¶

libidn2 is maintained as a Texinfo manual. If
the
info and
libidn2 programs are properly installed at your
site, the command
- info libidn2
should give you access to the complete manual.
