## Function Documentation

int readRPM | ( | const char * | fileName,
|  | Spec * | specp,
|  | struct rpmlead * | lead,
|  | Header * | sigs,
|  | CSA_t | csa
| ) |

  | Read rpm package components from file. Parameters:
  | filename | file name of package (or NULL to use stdin)
  Return values:
  | specp | spec structure to carry package header (or NULL)
  | lead | package lead
  | sigs | package signature
  Parameters:
  | csa |
Returns: 0 on success Definition at line 277 of file pack.c.

int writeRPM | ( | Header * | hdrp,
|  | const char * | fileName,
|  | int | type,
|  | CSA_t | csa,
|  | char * | passPhrase,
|  | const char ** | cookie
| ) |

  | Write rpm package to file. Warning: The first argument (header) is now passed by reference in order to return a reloaded contiguous header to the caller. Return values:
  | hdrp | header to write (final header is returned).
  Parameters:
  | filename | file name of package
  | type | RPMLEAD_SOURCE/RPMLEAD_BINARY
  | csa |
  | passPhrase |
  Return values:
  | cookie | generated cookie (i.e build host/time)
