Note that these functions are not located in the default library, libc.a, but in the mathematical library, libm.a. So when linking the application, the -lm option needs to be specified. #define DTOSTR_ALWAYS_SIGN   0x01 #define DTOSTR_PLUS_SIGN   0x02 #define DTOSTR_UPPERCASE   0x04 char * dtostre (double __val, char *__s, unsigned char __prec, unsigned char __flags) char * dtostrf (double __val, signed char __width, unsigned char __prec, char *__s) Defines #define _STDLIB_H_   1 #define __need_NULL #define __need_size_t #define __need_wchar_t #define __ptr_t   void * #define RAND_MAX   0x7FFF Typedefs typedef int(* __compar_fn_t )(const void *, const void *) Functions void abort (void) __ATTR_NORETURN__ int abs (int __i) long labs (long __i) void * bsearch (const void *__key, const void *__base, size_t __nmemb, size_t __size, int(*__compar)(const void *, const void *)) div_t div (int __num, int __denom) __asm__("__divmodhi4") ldiv_t ldiv (long __num, long __denom) __asm__("__divmodsi4") void qsort (void *__base, size_t __nmemb, size_t __size, __compar_fn_t __compar) long strtol (const char *__nptr, char **__endptr, int __base) unsigned long strtoul (const char *__nptr, char **__endptr, int __base) long atol (const char *__s) __ATTR_PURE__ int atoi (const char *__s) __ATTR_PURE__ void exit (int __status) __ATTR_NORETURN__ void * malloc (size_t __size) __ATTR_MALLOC__ void free (void *__ptr) void * calloc (size_t __nele, size_t __size) __ATTR_MALLOC__ void * realloc (void *__ptr, size_t __size) __ATTR_MALLOC__ double strtod (const char *__nptr, char **__endptr) double atof (const char *__nptr) int rand (void) void srand (unsigned int __seed) int rand_r (unsigned long *__ctx) Variables size_t __malloc_margin char * __malloc_heap_start char * __malloc_heap_end Automatically generated by Doxygen 1.5.6 on 4 Dec 2008.
