Macro Definition Documentation

CDIO_FREE_IF_NOT_NULL

#define CDIO_FREE_IF_NOT_NULL

(

p_obj

)

Value:

  if (NULL != p_obj) { free(p_obj); p_obj=NULL; };

free() and NULL out p_obj it is not already null.

CDIO_INLINE

#define CDIO_INLINE

CLAMP

#define CLAMP	(		x,
			low,
			high )

Value:

(((x) > (high)) ? (high) : (((x) < (low)) ? (low) : (x)))

IN

#define IN	(		x,
			low,
			high )

Value:

((x) >= (low) && (x) <= (high))

MAX

#define MAX	(		a,
			b )

Value:

(((a) > (b)) ? (a) : (b))

MIN

#define MIN	(		a,
			b )

Value:

(((a) < (b)) ? (a) : (b))

Function Documentation

_cdio_memdup()

void * _cdio_memdup	(	const void *	mem,
		size_t	count )

_cdio_strdup_fixpath()

char * _cdio_strdup_fixpath

(

const char

path[]

)

Duplicate path and make it platform compliant. Typically needed for MinGW/MSYS where a "/c/..." path must be translated to "c:/..." for use with fopen(), etc. Returned string must be freed by the caller using cdio_free().

_cdio_strdup_upper()

char * _cdio_strdup_upper

(

const char

str[]

)

_cdio_strfreev()

void _cdio_strfreev

(

char **

strv

)

_cdio_strlenv()

size_t _cdio_strlenv

(

char **

str_array

)

_cdio_strsplit()

char ** _cdio_strsplit	(	const char	str[],
		char	delim )

cdio_from_bcd8()

uint8_t cdio_from_bcd8

(

uint8_t

p

)

cdio_realpath()

char * cdio_realpath	(	const char *	psz_src,
		char *	psz_dst )

cdio_realpath() same as POSIX.1-2001 realpath if that's around. If not we do poor-man's simulation of that behavior.

cdio_to_bcd8()

uint8_t cdio_to_bcd8

(

uint8_t

n

)
