/****************************************************************************
* Name: lib_fileoutstream

*
* Description:
* Initializes a stream for use with a file descriptor.
* This function sets up the stream structure to enable writing to a file
* specified by the provide path. It initializes the necessary function
* pointers for character and string output, as well as the flush behavior.
*
* Input Parameters:
* stream - User allocated, uninitialized instance of struct
* lib_rawoutstream_s to be initialized.
* path - Path to file to open.
* oflag - Open flags.
* mode - Mode flags.
*
* Returned Value:
* 0 on success, negative error code in failuer.
