4.14 C library extensions
This section describes the ARM-specific library extensions and functions defined by the
C99 draft standard (ISO/IEC 9899:1999E). The extensions are summarized in
Table 4-22.
4.14.1 atoll()
The
atoll() function converts a decimal string into an integer, similarly to the ANSI
functions
atol() and atoi() , but returning a long long result. Like atoi() , atoll() can
accept octal or hexadecimal input if the string begins with
0 or 0x .
Syntax
longlong atoll(const char *nptr)
