Function Documentation

int malloc_check (  void    )

Check malloc list This operation is intended to help debug memory allocation problems with malloc and free. It verifies the consistency of internal data structures used by malloc and ensures that nothing is corrupted. Returns: 0 if there is no memory allocation problem

void malloc_dump (  void    )

Dump memory allocation list Dump the memory allocation lists to the standard output. The free list as well as allocated malloc blocks are printed.

char* ultoa (  unsigned long    val, char *    endp, int    base, int    mode, ...    )

Convert an unsigned long to a string. Convert an unsigned long to ASCII for printf purposes, returning a pointer to the first character of the string representation. Octal numbers can be forced to have a leading zero; hex numbers can be printed in upper or lower case. The mode controls various mode for the conversion: ULTOA_OCT_ZERO When set, a leading 0 is added for non-zero values for the octal conversions. ULTOA_UPPER When set, upper characters are used (hexadecimal conversions) ULTOA_GROUP The decimal conversion is made using groups of digits. The function takes two additional parameters: char thousep An additional character specifies the group separator. const char* grp Specifies the groups in terms of digits. A Parameters: val  Value to translate into a string endp  Pointer to end of buffer base  Base number for conversion (8, 10 or 16) mode  Control modes thousep  Optional character for thousand separator grp  Group string control Returns: the beginning of the string representation
