STRTOIMAX(P) POSIX Programmer's Manual STRTOIMAX(P)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(), str‐
toul(), 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 (accord‐
ing 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.
The following sections are informative.

APPLICATION USAGE
