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 feature_test_macros(7)):
Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
The stpncpy() function copies at most n characters from the string pointed to by src,
including the terminating null byte ('\0'), to the array pointed to by dest. Exactly n
characters are written at dest. If the length strlen(src) is smaller than n, the remain-
ing characters in the array pointed to by dest are filled with null bytes ('\0'), If the
length strlen(src) is greater or equal to n, the string pointed to by dest will not be
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 byte in dest, or, if dest is not null-
This function was added to POSIX.1-2008. Before that, it was a GNU extension.
