  48. * \brief Read formatted data from a stream.
  49. *
  50. * Similar to fscanf() except that the format string is expected in
  51. * program space.
  52. *
  53. * \param stream Pointer to a previously opened stream.
  54. * \param fmt Format string in program space containing conversion
  55. * specifications.
  56. *
  57. * \return The number of fields successfully converted and assigned.
  58. * The return value is EOF, if an error occurs or if the end
  59. * of the stream is reached before the first conversion.
  60. *
  61. * \warning The function will not check, if the stream pointer points
  62. * to a valid stream.
