NAME
atoi, atoi_l -- convert ASCII string to integer LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <stdlib.h> int atoi(const char *str); #include <xlocale.h> int atoi_l(const char *str, locale_t loc); DESCRIPTION
The atoi() function converts the initial portion of the string pointed to by str to int representation. It is equivalent to: (int)strtol(str, (char **)NULL, 10); While the atoi() function uses the current locale, the atoi_l() function may be passed a locale directly. See xlocale(3) for more informa- tion. IMPLEMENTATION NOTES
The atoi() and atoi_l() functions are thread-safe and async-cancel-safe. The atoi() and atoi_l() functions have been deprecated by strtol() and strtol_l() and should not be used in new code. ERRORS
The function atoi() need not affect the value of errno on an error. SEE ALSO
atof(3), atol(3), strtod(3), strtol(3), strtoul(3), xlocale(3) STANDARDS
The atoi() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1''), ISO/IEC 9899:1990 (``ISO C90''), and ISO/IEC 9899:1999 (``ISO C99''). BSD

NAME
atof, atof_l -- convert ASCII string to double LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <stdlib.h> double atof(const char *str); #include <xlocale.h> double atof_l(const char *str, locale_t loc); DESCRIPTION
The atof() function converts the initial portion of the string pointed to by str to double representation. It is equivalent to: strtod(str, (char **)NULL); The decimal point character is defined in the program's locale (category LC_NUMERIC). While the atof() function uses the current locale, the atof_l() function may be passed a locale directly. See xlocale(3) for more informa- tion. IMPLEMENTATION NOTES
The atof() and atof_l() functions are thread-safe and async-cancel-safe. The strtod() and strtod_l() functions are recommended instead of atof() and atof_l() functions, especially in new code. ERRORS
The function atof() need not affect the value of errno on an error. SEE ALSO
atoi(3), atol(3), strtod(3), strtol(3), strtoul(3), xlocale(3) STANDARDS
The atof() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1''), ISO/IEC 9899:1990 (``ISO C90''), and ISO/IEC 9899:1999 (``ISO C99''). BSD
