Convert a string into an integer
#include <inttypes.h> intmax_t strtoimax ( const char * nptr, char ** endptr, int base ); uintmax_t strtoumax ( const char * nptr, char ** endptr, int base );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The strtoimax() and strtoumax() functions are the same as the strtol(), strtoll(), strtoul(), and strtoull() functions except that they return objects of type intmax_t and uintmax_t.
The converted value.
If the correct value causes an overflow, INTMAX_MAX|UINTMAX_MAX or INTMAX_MIN is returned according to the sign and errno is set to ERANGE. If base is out of range, zero is returned and errno is set to EINVAL.
