Hi,

You said I had to map the current file at a seek point

but I just can't do itn there's a problem with the function mmap itself

here's my source: (from minimad)

int main(int argc, char *argv[]) { struct stat stat; void *fdm;

if (argc != 1) return 1;

int fd; FILE*fichier=fopen("essai.mp3","r+"); fd=fileno(fichier); lseek(fd,10,SEEK_SET); if (fstat(fd, &stat) == -1 || stat.st_size == 0) return 2; fdm = mmap(0,stat.st_size/2-1 , PROT_READ, MAP_SHARED, fd,stat.st_size/2); if (fdm == MAP_FAILED) return 3;

decode(fdm, stat.st_size/2-1);

if (munmap(fdm, stat.st_size/2-1) == -1) return 4;

return 0; }

I've got an error return 22

I know it's because the offset is not set to 0

thanks for your help
