Function Documentation

dotPreamble()

void dotPreamble	(	FILE *	out,
		const char *	graph_name,
		const char *	initial_comment
	)

Writes the first part of a dot file to the output stream: comments about how the graph was created and seed information

Definition at line 210 of file dot.c.

Referenced by outputEdge(), and writeDot().

endDot()

void endDot

(

FILE *

out

)

Writes the final '}'

Definition at line 217 of file dot.c.

Referenced by outputEdge(), and writeDot().

getNameFromDotFile()

void getNameFromDotFile

(

char *

buffer

)

Stores the name of the graph in the given buffer. Assumes the buffer is large enough.

Definition at line 167 of file dot.c.

References graph_name.

Referenced by allocateAdjacencyLists().

initDot()

void initDot

(

FILE *

in

)

Stores information about the dot file and advances the input to the point where edges can be read. NOTE: information in an initial comment is lost

Todo:

eventually will want to pick up the first comment

Here is the call graph for this function:

nextEdge()

bool nextEdge	(	FILE *	in,
		char *	source_buffer,
		char *	destination_buffer
	)

Reads the next edge from the input, storing the names of the vertices in buffers. Assumes the buffers are large enough.

Returns

true if another edge was found.

Here is the call graph for this function:

outputEdge()

void outputEdge	(	FILE *	out,
		const char *	src,
		const char *	dst
	)

Writes the edge (src, dst) to the output
