ECVT_R(3) Linux Programmer's Manual ECVT_R(3)NAME
ecvt_r, fcvt_r, qecvt_r, qfcvt_r - convert a floating-point number to a string
SYNOPSIS
#include <stdlib.h>
int ecvt_r(double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
int fcvt_r(double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
int qecvt_r(long double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
int qfcvt_r(long double number, int ndigits, int *decpt,
int *sign, char *buf, size_t len);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
ecvt_r(), fcvt_r(), qecvt_r(), qfcvt_r(): _SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE >= 500
DESCRIPTION
The functions ecvt_r(), fcvt_r(), qecvt_r() and qfcvt_r() are identical to ecvt(3), fcvt(3), qecvt(3) and qfcvt(3), respectively, except
that they do not return their result in a static buffer, but instead use the supplied buf of size len. See ecvt(3) and qecvt(3).
RETURN VALUE
These functions return 0 on success, and -1 otherwise.
CONFORMING TO
These functions are GNU extensions.
NOTES
These functions are obsolete. Instead, sprintf(3) is recommended.

ecvt, fcvt - convert a floating-point number to a string
SYNOPSIS
#include <stdlib.h>
char *ecvt(double number, int ndigits, int *decpt, int *sign);
char *fcvt(double number, int ndigits, int *decpt, int *sign);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
ecvt(), fcvt(): _SVID_SOURCE || _XOPEN_SOURCE >= 500
DESCRIPTION
The ecvt() function converts number to a null-terminated string of ndigits digits (where ndigits is reduced to a system-specific limit
determined by the precision of a double), and returns a pointer to the string. The high-order digit is nonzero, unless number is zero.
The low order digit is rounded. The string itself does not contain a decimal point; however, the position of the decimal point relative to
the start of the string is stored in *decpt. A negative value for *decpt means that the decimal point is to the left of the start of the
string. If the sign of number is negative, *sign is set to a nonzero value, otherwise it is set to 0. If number is zero, it is unspeci-
fied whether *decpt is 0 or 1.
The fcvt() function is identical to ecvt(), except that ndigits specifies the number of digits after the decimal point.
RETURN VALUE
Both the ecvt() and fcvt() functions return a pointer to a static string containing the ASCII representation of number. The static string
is overwritten by each call to ecvt() or fcvt().
CONFORMING TO
SVr2; marked as LEGACY in POSIX.1-2001. POSIX.1-2008 removes the specifications of ecvt() and fcvt(), recommending the use of sprintf(3)
instead (though snprintf(3) may be preferable).
NOTES
Linux libc4 and libc5 specified the type of ndigits as size_t. Not all locales use a point as the radix character ("decimal point").

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.

Hello for all,
I am testing the behavior of a 32 bit application running on Solaris 5.10 (SPARC), and realize it reaches 4GB of memory and then crashes.
