Defines
#define	pa_xnew(type, n)   ((type*) _pa_xnew_internal((n), sizeof(type)))
	Allocate n new structures of the specified type.
#define	pa_xnew0(type, n)   ((type*) _pa_xnew0_internal((n), sizeof(type)))
	Same as pa_xnew() but set the memory to zero.
#define	pa_xnewdup(type, p, n)   ((type*) _pa_xnewdup_internal((p), (n), sizeof(type)))
	Same as pa_xnew() but duplicate the specified data.
#define	pa_xrenew(type, p, n)   ((type*) _pa_xrenew_internal(p, (n), sizeof(type)))
	Reallocate n new structures of the specified type.
Functions
void *	pa_xmalloc (size_t l) PA_GCC_MALLOC PA_GCC_ALLOC_SIZE(1)
	Allocate the specified number of bytes, just like malloc() does.
void *	pa_xmalloc0 (size_t l) PA_GCC_MALLOC PA_GCC_ALLOC_SIZE(1)
	Same as pa_xmalloc(), but initialize allocated memory to 0.
void *	pa_xrealloc (void *ptr, size_t size) PA_GCC_ALLOC_SIZE(2)
	The combination of pa_xmalloc() and realloc()
void	pa_xfree (void *p)
	Free allocated memory.
char *	pa_xstrdup (const char *s) PA_GCC_MALLOC
	Duplicate the specified string, allocating memory with pa_xmalloc()
char *	pa_xstrndup (const char *s, size_t l) PA_GCC_MALLOC
	Duplicate the specified string, but truncate after l characters.
void *	pa_xmemdup (const void *p, size_t l) PA_GCC_MALLOC PA_GCC_ALLOC_SIZE(2)
	Duplicate the specified memory block.

Define Documentation

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

Allocate n new structures of the specified type.

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

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

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

Same as pa_xnew() but duplicate the specified data.

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

Function Documentation

void pa_xfree

(

void *

p )

Free allocated memory.

void* pa_xmalloc

(

size_t

l )

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

However, in case of OOM, terminate

void* pa_xmalloc0

(

size_t

l )

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

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

Duplicate the specified memory block.

void* pa_xrealloc	(	void *	ptr,
		size_t	size
	)

The combination of pa_xmalloc() and realloc()

char* pa_xstrdup

(

const char *

s )

Duplicate the specified string, allocating memory with pa_xmalloc()

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

Duplicate the specified string, but truncate after l characters.
