## Detailed Description

File Info Set API.

## Typedef Documentation

## rpmFileAction

typedef enum rpmFileAction_e rpmFileAction

File disposition(s) during package install/erase transaction.

## rpmFileTypes

typedef enum rpmFileTypes_e rpmFileTypes

File types. These are the file types used internally by rpm. The file type is determined by applying stat(2) macros like S_ISDIR to the file mode tag from a header. The values are arbitrary, but are identical to the linux stat(2) file types.

## Enumeration Type Documentation

## rpmFileAction_e

enum rpmFileAction_e
