.TH TS_LIBVERSION 3  "" "" "tslib"
.SH NAME
ts_libversion \- get version information on the currently running tslib
.SH SYNOPSIS
.nf
.B #include <tslib.h>
.sp
.BI "struct ts_lib_version_data *ts_libversion();"
.sp
.fi

.SH DESCRIPTION
.BR ts_libversion ()
This function returns a pointer to a static copy of the version info struct:

.nf
struct ts_lib_version_data {
        const char      *package_version;
        int             version_num;
        unsigned int    features;
};
.fi

.BR package_version
is just the string containing the tarball release number, e.g. "1.10".

.BR version_num
is a 24 bit number created like this: <8 bits major number> | <8 bits minor number> | <8 bits patch number> of the library libts. Version 0.7.1 is therefore returned as 0x000701.

.BR features
can have one or more bits set. The currently defined bits are:
.RS 4
.BR TSLIB_VERSION_MT
tslib filters support multitouch ts_read_mt() and there is at least one raw access module supporting it (currently evdev input)
.BR TSLIB_VERSION_OPEN_RESTRICTED
ts_open_restricted and ts_close_restricted function pointers are available to implement
.BR TSLIB_VERSION_EVENTPATH
ts_get_eventpath() is available since tslib can auto-detect a device
.BR TSLIB_VERSION_VERSION
simple tslib_version() and ts_print_ascii_logo() are available
.RE
.SH RETURN VALUE
This function returns a pointer to a static copy of the version info struct.
