Function Documentation

void freez ( void * vpt )

Free pointer and set it to NULL.

s = needMem(1024); ... freez(&s);

Definition at line 135 of file common.c.

void* needLargeMem ( size_t size )

Request a large block of memory.

This calls abort if the memory allocation fails. The memory is not initialized to zero.

Definition at line 52 of file common.c.

void* needLargeMemResize	(	void *	vp,
		size_t	size
	)

Adjust memory size on a block, possibly relocating it.

If vp is NULL, a new memory block is allocated. Memory not initted.

Definition at line 78 of file common.c.

void* needLargeZeroedMemResize	(	void *	vp,
		size_t	oldSize,
		size_t	newSize
	)

Adjust memory size on a block, possibly relocating it.

If vp is NULL, a new memory block is allocated. If block is grown, new memory is zeroed.

Definition at line 96 of file common.c.

void* needMem ( size_t size )

Request a block of memory.

Need mem calls abort if the memory allocation fails. The memory is initialized to zero.

Definition at line 38 of file common.c.

Texta readList ( char * fileName )

Read a list from a file.

Note:: Empty lines are skipped.
