Device and method for executing kernel api interactively

A device and a method for interactively executing a kernel API(Application Program Interface) are provided to perform only an additional kernel API in a user area without repeating the entire kernel program development steps, thereby checking operation result of the additional kernel API. A device interface unit(310) receives a command from a user and outputs an execution result of the command to the user. A kernel API command analyzing unit(320) receives a command from a device interface unit. The kernel API command analyzing unit parses a command through a kernel API name and a medium variable to generate kernel API execution information. The kernel API execution information includes the kernel API name and the medium variable. A kernel API command execution unit(340) executes a kernel API corresponding to a command by using the kernel API execution information to transmit the execution result to the device interface unit.
