NAME

src/res_lea.c - Resource allocation using malloc

DESCRIPTION

This file provides alternative implementations of memory allocation function found in src/resources.c. It is used if Configure.pl is passed the --gc=malloc or --gc=malloc-trace options.

The "lea" in the file name refers to Doug Lea, who wrote malloc implementation found in src/malloc.c.

Functions

void Parrot_go_collect(Interp *interpreter): Does nothing other than increment the iterpreter's collect_runs count.
static PARROT_INLINE void *xmalloc(size_t size): Obtains the memory from malloc() and returns it. Panics if there is no memory available.
static PARROT_INLINE void *xcalloc(size_t n, size_t size): Obtains the memory from calloc() and returns it. Panics if there is no memory available.
static PARROT_INLINE void *xrealloc(void *p, size_t size): Reallocates the memory with realloc() and returns it. Panics if there is no memory available.
void *Parrot_reallocate(Interp *interpreter, void *from, size_t size): COWable objects (strings or Buffers) use an INTVAL at bufstart for refcounting in DOD. bufstart is incremented by that INTVAL.
void *Parrot_allocate(Interp *interpreter, void *buffer, size_t size): Allocates and returns the required memory. size is the number of bytes of memory required.
void *Parrot_allocate_zeroed(Interp *interpreter, void *buffer, size_t size): Allocates, zeros and returns the required memory. size is the number in bytes of memory required.
void *Parrot_reallocate_string(Interp *interpreter, STRING *str, size_t size): Reallocates the string buffer in *str and returns it. size is the number of bytes memory required.
void *Parrot_allocate_string(Interp *interpreter, STRING *str, size_t size): Allocates the string buffer in *str and returns it. size is the number bytes of memory required.
void Parrot_initialize_memory_pools(Interp *interpreter): Does nothing.
void Parrot_destroy_memory_pools(Interp *interpreter): Does nothing.
