  6.         atoll
  7. INDEX
  8.         _atoll_r
  9.  
  10. ANSI_SYNOPSIS
  11.         #include <stdlib.h>
  12.         long long atoll(const char *<[str]>);
  13.         long long _atoll_r(struct _reent *<[ptr]>, const char *<[str]>);
  14.  
  15. TRAD_SYNOPSIS
  16.         #include <stdlib.h>
  17.         long long atoll(<[str]>)
  18.         const char *<[str]>;
  19.  
  20.         long long _atoll_r(<[ptr]>, <[str]>)
  21.         struct _reent *<[ptr]>;
  22.         const char *<[str]>;
  23.  
  24. DESCRIPTION
  25. The function <<atoll>> converts the initial portion of the string
  26. pointed to by <<*<[str]>>> to a type <<long long>>.  A call to
  27. atoll(str) in this implementation is equivalent to
  28. strtoll(str, (char **)NULL, 10) including behavior on error.
  29.  
  30. The alternate function <<_atoll_r>> is a reentrant version.  The
  31. extra argument <[reent]> is a pointer to a reentrancy structure.
  32.  
  33.  
  34. RETURNS
  35. The converted value.
  36.  
  37. PORTABILITY
  38. <<atoll>> is ISO 9899 (C99) and POSIX 1003.1-2001 compatable.
  39.  
  40. No supporting OS subroutines are required.
