Datatype: AjPFilebuff

Function is for manipulating buffered input files and returns or takes at least one AjPFilebuff argument.

Sections:

buffered file line read operations Input

AjPFilebuff: buffered file line read operations

Functions:

ajBuffreadLine Reads a line from a buffered file. If the buffer has data, reads from the buffer. If the buffer is exhausted, reads from the file. If the file is exhausted, sets end of file and returns. If end of file was already set, looks for another file to open.

ajBuffreadLinePos Reads a line from a buffered file. If the buffer has data, reads from the buffer. If the buffer is exhausted, reads from the file. If the file is exhausted, sets end of file and returns. If end of file was already set, looks for another file to open.

ajBuffreadLinePosStore Reads a line from a buffered file. Also appends the line to a given string if the append flag is true. A double NULL character is added afterwards. If the buffer has data, reads from the buffer. If the buffer is exhausted, reads from the file. If the file is exhausted, sets end of file and returns. If end of file was already set, looks for another file to open.
