stpncpy — copy a fixed-size string, returning a pointer to its end
#define _GNU_SOURCE #include <string.h>
char
*stpncpy( |
char * | dest, |
| const char * | src, | |
| size_t | n); |
The stpncpy() function
copies at most n
characters from the string pointed to by src, including the terminating
'\0' character, to the array pointed to by dest. Exactly n characters are written at
dest. If the length
strlen(src) is
smaller than n, the
remaining characters in the array pointed to by dest are filled with '\0'
characters. If the length strlen(src) is greater or
equal to n, the
string pointed to by dest will not be '\0'
terminated.
The strings may not overlap.
The programmer must ensure that there is room for at least
n characters at
dest.
stpncpy() returns a pointer
to the terminating null in dest, or, if dest is not null-terminated,
dest + n.
