    NAME

    sysfs - get file system type information
     
    

    SYNOPSIS

    #include <sys/fstyp.h>
    #include <sys/fsid.h>
    
    int sysfs(int opcode, const char *fsname);
    

    int sysfs(int opcode, int fs_index, char *buf);
    

    int sysfs(int opcode);
    

     

    DESCRIPTION

    The sysfs() function returns information about the file system types configured in the system. The number of arguments accepted by sysfs() depends on the opcode argument, which can take the following values:

    GETFSIND

    Translate fsname, a null-terminated file-system type identifier, into a file-system type index.

    GETFSTYP

    Translate fs_index, a file-system type index, into a null-terminated file-system type identifier and write it into the buffer pointed to by buf, which must be at least of size FSTYPSZ as defined in <sys/fstyp.h>.

    GETNFSTYP

    Return the total number of file system types configured in the system.

     

    RETURN VALUES

    Upon successful completion, the value returned depends upon the opcode argument as follows:

    GETFSIND

    the file-system type index

    GETFSTYP

    0

    GETNFSTYP

    the number of file system types configured

    Otherwise, -1 is returned and errno is set to indicate the error.  

    ERRORS

    The sysfs() function will fail if:

    EFAULT

    The buf or fsname argument points to an illegal address.

    EINVAL

    The fsname argument points to an invalid file-system identifier; the fs_index argument is 0 or invalid; or the opcode argument is invalid.
