    Parameters:

    prefix
    leading part of temp file path

    Return values:

    fnptr
    temp file name (or NULL)
    fdptr
    temp file handle

    Returns: 0 on success

    Referenced by doGetRecord(), packageBinaries(), readPackageHeaders(), and writeRPM().  

    void rpmBuildFileList (Header h, const char *** fileListPtr, int * fileCountPtr)

    Retrieve file names from header.

    The representation of file names in package headers changed in rpm-4.0. Originally, file names were stored as an array of paths. In rpm-4.0, file names are stored as separate arrays of dirname's and basename's, with a dirname index to associate the correct dirname with each basname. This function is used to retrieve file names independent of how the file names are represented in the package header.

    Parameters:

    h
    header

    Return values:

    fileListPtr
    address of array of file names
    fileCountPtr
    address of number of files

    int rpmHeaderGetEntry (Header h, int_32 tag, int_32 * type, void ** p, int_32 * c)

    Retrieve tag info from header.

    This is a 'dressed' entry to headerGetEntry to do: 1) DIRNAME/BASENAME/DIRINDICES -> FILENAMES tag conversions. 2) i18n lookaside (if enabled).

    Parameters:

    h
    header
    tag
    tag

    Return values:

    type
    address of tag value data type
    p
    address of pointer to tag value(s)
    c
    address of number of values

    Returns: 0 on success, 1 on bad magic, 2 on error

    int rpmPackageGetEntry (void * leadp, Header sigs, Header h, int_32 tag, int_32 * type, void ** p, int_32 * c)

    Retrieve tag info from header.

    Yet Another 'dressed' entry to headerGetEntry in order to unify signature/header tag retrieval.

    Deprecated: Signature tags are now duplicated into header when installed.

    Todo: Eliminate from API.

    Parameters:

    leadp
    rpm lead
    h
    header
    sigs
    signatures
    tag
    tag

    Return values:

    type
    address of tag value data type
    p
    address of pointer to tag value(s)
    c
    address of number of values

    Returns: 0 on success, 1 on bad magic, 2 on error

    char** splitString (const char * str, int length, char sep)

    Split string into fields separated by a character.

    Parameters:

    str
    string
    length
    length of string
    sep
    separator character

    Returns: (malloc'd) argv array
