Get the FUSE version string

Question

Is there a function that returns the FUSE version string?

fuse_common.h has int fuse_version(void), which returns the major version, multiplied by 10, plus the minor version; both of which are derived from #define values. (e.g., This returns 27 on my platform). What I'm looking for, however, is some char* fuse_version(void) that would return something like 2.7.3.

As you said yourself, the version is defined in fuse_common.h. If you don't want to use helper_version, as @Alexguitar said you may just write a small program that does it -- but it seems that only the two first numbers (major and minor) are available:

#include <fuse/fuse.h>
#include <stdlib.h>
#include <stdio.h>

char* str_fuse_version(void) {
    static char str[10] = {0,0,0,0,0,0,0,0,0,0};
    if (str[0]==0) {
        int v = fuse_version();
        int a = v/10;
        int b = v%10;
        snprintf(str,10,"%d.%d",a,b); 
    }
    return str;
}


int main () {
    printf("%s\n", str_fuse_version());
    exit(EXIT_SUCCESS);
}

Note: you should include fuse/fuse.h and not fuse_common.h; also, you may need to pass -D_FILE_OFFSET_BITS=64 when compiling.

$ gcc -Wall fuseversiontest.c -D_FILE_OFFSET_BITS=64  -lfuse

$ ./a.out
