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.
Functions
void *	pa_xmalloc (size_t l)
	Allocate the specified number of bytes, just like malloc() does.
void *	pa_xmalloc0 (size_t l)
	Same as pa_xmalloc(), but initialize allocated memory to 0.
void *	pa_xrealloc (void *ptr, size_t size)
	The combination of pa_xmalloc() and realloc().
void	pa_xfree (void *p)
	Free allocated memory.
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.
void *	pa_xmemdup (const void *p, size_t l)
	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.

Function Documentation

void pa_xfree (  void *  p  )

Free allocated memory. Examples: pacat.c, and paplay.c.

void* pa_xmalloc (  size_t  l  )

Allocate the specified number of bytes, just like malloc() does. However, in case of OOM, terminate Examples: pacat.c, and paplay.c.

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(). Examples: pacat.c, and paplay.c.

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

Duplicate the specified string, but truncate after l characters.
