Macros
#define	SPEEX_COPY(dst, src, n)   (memcpy((dst), (src), (n)*sizeof(*(dst)) + 0*((dst)-(src)) ))
	Copy n elements from src to dst.
#define	SPEEX_MOVE(dst, src, n)   (memmove((dst), (src), (n)*sizeof(*(dst)) + 0*((dst)-(src)) ))
	Copy n elements from src to dst, allowing overlapping regions.
#define	SPEEX_MEMSET(dst, c, n)   (memset((dst), (c), (n)*sizeof(*(dst))))
	For n elements worth of memory, set every byte to the value of c, starting at address dst.
#define	speex_fatal(str)   _speex_fatal(str, __FILE__, __LINE__);

Functions
static void *	speex_alloc (int size)
	Speex wrapper for calloc.
static void *	speex_alloc_scratch (int size)
	Same as speex_alloc, except that the area is only needed inside a Speex call (might cause problem with wideband though)
static void *	speex_realloc (void *ptr, int size)
	Speex wrapper for realloc.
static void	speex_free (void *ptr)
	Speex wrapper for calloc.
static void	speex_free_scratch (void *ptr)
	Same as speex_free, except that the area is only needed inside a Speex call (might cause problem with wideband though)
static void	_speex_fatal (const char *str, const char *file, int line)
static void	speex_warning (const char *str)
static void	speex_warning_int (const char *str, int val)
static void	speex_notify (const char *str)
static void	_speex_putc (int ch, void *file)
	Speex wrapper for putc.
static void	print_vec (float *vec, int len, char *name)

SPEEX_COPY

#define SPEEX_COPY	(		dst,
			src,
			n )   (memcpy((dst), (src), (n)*sizeof(*(dst)) + 0*((dst)-(src)) ))

Copy n elements from src to dst.

The 0* term provides compile-time type checking

Definition at line 100 of file os_support.h.

speex_fatal

#define speex_fatal

(

str

)

_speex_fatal(str, __FILE__, __LINE__);

Definition at line 159 of file os_support.h.

SPEEX_MEMSET

#define SPEEX_MEMSET	(		dst,
			c,
			n )   (memset((dst), (c), (n)*sizeof(*(dst))))

For n elements worth of memory, set every byte to the value of c, starting at address dst.

Definition at line 111 of file os_support.h.

SPEEX_MOVE

#define SPEEX_MOVE	(		dst,
			src,
			n )   (memmove((dst), (src), (n)*sizeof(*(dst)) + 0*((dst)-(src)) ))

Copy n elements from src to dst, allowing overlapping regions.

The 0* term provides compile-time type checking

Function Documentation

_speex_fatal()

static void _speex_fatal ( const char * str, const char * file, int line )

inlinestatic

Definition at line 116 of file os_support.h.

_speex_putc()

static void _speex_putc ( int ch, void * file )

inlinestatic

Speex wrapper for putc.

Definition at line 152 of file os_support.h.

print_vec()

static void print_vec ( float * vec, int len, char * name )

inlinestatic

Definition at line 163 of file os_support.h.

speex_alloc()

static void * speex_alloc ( int size )

inlinestatic

Speex wrapper for calloc.

To do your own dynamic allocation, all you need to do is replace this function, speex_realloc and speex_free NOTE: speex_alloc needs to CLEAR THE MEMORY

Definition at line 56 of file os_support.h.

speex_alloc_scratch()

static void * speex_alloc_scratch ( int size )

inlinestatic

Same as speex_alloc, except that the area is only needed inside a Speex call (might cause problem with wideband though)

Definition at line 67 of file os_support.h.

speex_free()

static void speex_free ( void * ptr )

inlinestatic

Speex wrapper for calloc.

To do your own dynamic allocation, all you need to do is replace this function, speex_realloc and speex_alloc

Definition at line 84 of file os_support.h.

speex_free_scratch()

static void speex_free_scratch ( void * ptr )

inlinestatic

Same as speex_free, except that the area is only needed inside a Speex call (might cause problem with wideband though)

Definition at line 92 of file os_support.h.

speex_notify()

static void speex_notify ( const char * str )

inlinestatic

Definition at line 142 of file os_support.h.

speex_realloc()

static void * speex_realloc ( void * ptr, int size )

inlinestatic

Speex wrapper for realloc.

To do your own dynamic allocation, all you need to do is replace this function, speex_alloc and speex_free

Definition at line 76 of file os_support.h.

speex_warning()

static void speex_warning ( const char * str )

inlinestatic

Definition at line 124 of file os_support.h.

inlinestatic

Definition at line 133 of file os_support.h.
