Function parse_input_filename 

pub fn parse_input_filename<'a>(
    output_buf: &'a mut [u8; 64],
    input_name: &str,
    category: FileCategory,
) -> Result<&'a str>

Parses a filename from an input string, applying default path and extension.

This function uses cFE’s logic to construct a complete, platform-correct file path. If the input_name omits a path or extension, defaults appropriate for the category are applied.

Arguments

• output_buf: A buffer to store the resulting fully-qualified path.
• input_name: The (potentially partial) filename to parse.
• category: The FileCategory which determines the default path and extension.

Returns

On success, returns a &str slice of the valid, null-terminated path within output_buf.
