Functions¶

Variables¶

size_t __malloc_margin char * __malloc_heap_start char * __malloc_heap_end

Non-standard (i.e. non-ISO C) functions.¶

#define RANDOM_MAX 0x7FFFFFFF char * itoa (int val, char *s, int radix) char * ltoa (long val, char *s, int radix) char * utoa (unsigned int val, char *s, int radix) char * ultoa (unsigned long val, char *s, int radix) long random (void) void srandom (unsigned long __seed) long random_r (unsigned long *__ctx)

Conversion functions for double arguments.¶

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 /* put '+' or ' ' for positives */ #define DTOSTR_PLUS_SIGN 0x02 /* put '+' rather than ' ' */ #define DTOSTR_UPPERCASE 0x04 /* put 'E' rather 'e' */ #define EXIT_SUCCESS 0 #define EXIT_FAILURE 1 char * dtostre (double __val, char *__s, unsigned char __prec, unsigned char __flags) char * dtostrf (double __val, signed char __width, unsigned char __prec, char *__s)
