  @brief	A version of strstr supporting NULL characters.

  This module offers a single function: memstr(), which acts just like
  strstr(), except that it also supports NULL characters in the string
  to search.

  This is useful e.g. when searching a binary file for an ASCII key.

  @brief    find a char string in a char memory block

  @param    pattern Character string to look for
  @return   char pointer to the pattern in block, or NULL.

  Find a char pattern in a char memory block. This does not support
  regular expressions. The functionality is strictly similar to
  strstr(), except that the searched block is allowed to contain NULL
  characters.
