Detailed Description

Memory allocation functions.

Macro Definition Documentation

pa_xnew

#define pa_xnew	(		type,
			n
	)		((type*) _pa_xnew_internal((n), sizeof(type)))

Allocate n new structures of the specified type.

pa_xnew0

#define pa_xnew0	(		type,
			n
	)		((type*) _pa_xnew0_internal((n), sizeof(type)))

Same as pa_xnew() but set the memory to zero.

pa_xnewdup

#define pa_xnewdup	(		type,
			p,
			n
	)		((type*) _pa_xnewdup_internal((p), (n), sizeof(type)))

Same as pa_xnew() but duplicate the specified data.

pa_xrenew

#define pa_xrenew	(		type,
			p,
			n
	)		((type*) _pa_xrenew_internal(p, (n), sizeof(type)))

Reallocate n new structures of the specified type.

Function Documentation

pa_xfree()

void pa_xfree

(

void *

p

)

Free allocated memory.

pa_xmalloc()

void* pa_xmalloc

(

size_t

l

)

Allocate the specified number of bytes, just like malloc() does.

However, in case of OOM, terminate

pa_xmalloc0()

void* pa_xmalloc0

(

size_t

l

)

Same as pa_xmalloc(), but initialize allocated memory to 0.

pa_xmemdup()

void* pa_xmemdup	(	const void *	p,
		size_t	l
	)

Duplicate the specified memory block.

pa_xrealloc()

void* pa_xrealloc	(	void *	ptr,
		size_t	size
	)

The combination of pa_xmalloc() and realloc()

pa_xstrdup()

char* pa_xstrdup

(

const char *

s

)

Duplicate the specified string, allocating memory with pa_xmalloc()

pa_xstrndup()

char* pa_xstrndup	(	const char *	s,
		size_t	l
	)

Duplicate the specified string, but truncate after l characters.
