ATOL(P) POSIX Programmer's Manual ATOL(P)NAMEatol, atoll - convert a string to a long integerSYNOPSIS#include <stdlib.h> long atol(const char *str); long long atoll(const char *nptr);DESCRIPTIONThe call atol(str) shall be equivalent to: strtol(str, (char **)NULL, 10) The call atoll(str) shall be equivalent to: strtoll(nptr, (char **)NULL, 10) except that the handling of errors may differ. If the value cannot be represented, the behavior is undefined.RETURN VALUEThese functions shall return the converted value if the value can be represented.ERRORSNo errors are defined. The following sections are informative.EXAMPLESNone.APPLICATION USAGEThe atol() function is subsumed by strtol() but is retained because it is used extensively in existing code. If the number is not known to be in range, strtol() should be used because atol() is not required to perform any error checking.RATIONALENone.FUTURE DIRECTIONSNone.SEE ALSOstrtol() , the Base Definitions volume of IEEE Std 1003.1-2001, <stdlib.h>COPYRIGHTPortions of this text are reprinted and reproduced in electronic form from IEEE Std 1003.1, 2003 Edition, Standard for Information Technol- ogy -- Portable Operating System Interface (POSIX), The Open Group Base Specifications Issue 6, Copyright (C) 2001-2003 by the Institute of Electrical and Electronics Engineers, Inc and The Open Group.
