NAME

strtoimax, strtoumax - convert string to integer type  

SYNOPSIS

#include <inttypes.h>

intmax_t strtoimax(const char *restrict nptr, char **restrict endptr,
       int
base);
uintmax_t strtoumax(const char *restrict
nptr, char **restrict endptr,
       int
base);
 

DESCRIPTION

These functions shall be equivalent to the strtol(), strtoll(), strtoul(), and strtoull() functions, except that the initial portion of the string shall be converted to intmax_t and uintmax_t representation, respectively.  

RETURN VALUE

These functions shall return the converted value, if any.

If no conversion could be performed, zero shall be returned.

If the correct value is outside the range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall be returned (according to the return type and sign of the value, if any), and errno shall be set to [ERANGE].  

ERRORS

These functions shall fail if:

ERANGE
The value to be returned is not representable.

These functions may fail if:

EINVAL
The value of base is not supported.
