wcstoimax(), wcstoumax()

Convert a wide-character string into an integer

Synopsis:

#include <inttypes.h>

intmax_t wcstoimax ( const wchar_t * nptr,
                     wchar_t ** endptr,
                     int base );

uintmax_t wcstoumax ( const wchar_t * nptr,
                      wchar_t ** endptr,
                      int base );

Arguments:

nptr
A pointer to the string to parse.
endptr
If this argument isn't NULL, the function stores in it a pointer to the first unrecognized character found in the string.
base
The base of the number being parsed:

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The wcstoimax() and wcstoumax() functions are the same as the wcstol(), wcstoll(), wcstoul(), and wcstoull() functions except that they return objects of type intmax_t and uintmax_t.

Returns:

The converted value.

If the correct value causes an overflow, INTMAX_MAX, UINTMAX_MAX, or INTMAX_MIN is returned, depending on the function and the sign, and errno is set to ERANGE. If base is out of range, zero is returned and errno is set to EINVAL.

Classification:

ANSI, POSIX 1003.1

Safety:
Cancellation point No
Interrupt handler Yes
Signal handler Yes
Thread Yes
