fmt_ulong(3) Library Functions Manual fmt_ulong(3)NAME
fmt_ulong - write an ASCII representation of an unsigned long integer
SYNTAX
#include <fmt.h>
size_t fmt_ulong(char *dest,unsigned long source);
DESCRIPTION
fmt_ulong writes an ASCII representation ('0' to '9', base 10) of source to dest and returns the number of bytes written.
fmt_ulong does not append .
If dest equals FMT_LEN (i.e. is zero), fmt_ulong returns the number of bytes it would have written.
For convenience, fmt.h defines the integer FMT_ULONG to be big enough to contain every possible fmt_ulong output plus .

strcat, strncat - concatenate two strings
SYNOPSIS
#include <string.h>
char *strcat(char *dest, const char *src);
char *strncat(char *dest, const char *src, size_t n);
DESCRIPTION
The strcat() function appends the src string to the dest string, overwriting the null byte (' ') at the end of dest, and then adds a ter-
minating null byte. The strings may not overlap, and the dest string must have enough space for the result.
The strncat() function is similar, except that
* it will use at most n characters from src; and
* src does not need to be null-terminated if it contains n or more characters.
As with strcat(), the resulting string in dest is always null-terminated.
If src contains n or more characters, strncat() writes n+1 characters to dest (n from src plus the terminating null byte). Therefore, the
size of dest must be at least strlen(dest)+n+1.
A simple implementation of strncat() might be:
char*
strncat(char *dest, const char *src, size_t n)
{
size_t dest_len = strlen(dest);
size_t i;
for (i = 0 ; i < n && src[i] != ' ' ; i++)
dest[dest_len + i] = src[i];
dest[dest_len + i] = ' ';
return dest;
}
RETURN VALUE
The strcat() and strncat() functions return a pointer to the resulting string dest.
