Detailed Description

Memory allocation functions.

Macro Definition Documentation

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

Allocate n new structures of the specified type.

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

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

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

Same as pa_xnew() but duplicate the specified data.

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

Reallocate n new structures of the specified 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.
