-.Dt ATOL 3
-.Os
-.Sh NAME
-.Nm atol , atoll ,
-.Nm atol_l , atoll_l
-.Nd convert
-.Tn ASCII
-string to
-.Vt long
-or
-.Vt "long long"
-integer
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft long
-.Fn atol "const char *str"
-.Ft "long long"
-.Fn atoll "const char *str"
-.In xlocale.h
-.Ft long
-.Fn atol_l "const char *str" "locale_t loc"
-.Ft "long long"
-.Fn atoll_l "const char *str" "locale_t loc"
-.Sh DESCRIPTION
-The
-.Fn atol
-function converts the initial portion of the string pointed to by
-.Fa str
-to
-.Vt long
-integer
-representation.
-.Pp
-It is equivalent to:
-.Pp
-.Dl "strtol(str, (char **)NULL, 10);"
-.Pp
-The
-.Fn atoll
-function converts the initial portion of the string pointed to by
-.Fa str
-to
-.Vt "long long"
-integer
-representation.
-.Pp
-It is equivalent to:
-.Pp
-.Dl "strtoll(str, (char **)NULL, 10);"
-.Pp
-While the
-.Fn atol
-and
-.Fn atoll
-functions use the current locale, the
-.Fn atol_l
-and
-.Fn atoll_l
-functions may be passed locales directly. See
-.Xr xlocale 3
-for more information.
-.Sh IMPLEMENTATION NOTES
-The
-.Fn atol ,
-.Fn atoll ,
-.Fn atol_l ,
-and
-.Fn atoll_l
-functions are thread-safe and async-cancel-safe.
-.Pp
-The
-.Fx
-implementations of the
-.Fn atol
-and
-.Fn atoll
-functions are thin wrappers around
-.Fn strtol
-and
-.Fn stroll
-respectively, so these functions will affect the value of
-.Va errno
-in the same way that the
-.Fn strtol
-and
-.Fn stroll
-functions are able to.
-This behavior of
-.Fn atol
-and
-.Fn atoll
-is not required by
-.St -isoC
-or
-.St -isoC-99 ,
-but it is allowed by all of
-.St -isoC , St -isoC-99
-and
-.St -p1003.1-2001 .
-.Sh ERRORS
-The functions
-.Fn atol
-and
-.Fn atoll
-may affect the value of
-.Va errno
-on an error.
-.Sh SEE ALSO
-.Xr atof 3 ,
-.Xr atoi 3 ,
-.Xr strtod 3 ,
-.Xr strtol 3 ,
-.Xr strtoul 3 ,
-.Xr xlocale 3
-.Sh STANDARDS
-The
-.Fn atol
-function
-conforms to
-.St -isoC .
-The
-.Fn atoll
-function
-conforms to
-.St -isoC-99 .
