stpncpy - copy a fixed-size string, returning a pointer to its end
char *stpncpy(char *dest, const char *src, size_t n);
Feature Test Macro Requirements for glibc (see
- Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
- Before glibc 2.10:
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
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
returns a pointer to the terminating null
in dest, or, if dest is not null-terminated,
dest + n.
This function is a GNU extension.
