strtok_r
char * strtok_r(char *str, const char *sep, char **state)
Tokenize a string into tokens (reentrant).
stpncpy
char * stpncpy(char *ZRESTRICT s1, const char *ZRESTRICT s2, size_t n)
Copy at most n bytes of a string and return a pointer to the terminating NUL byte.
strdup
char * strdup(const char *s)
Duplicate a string.
strndup
char * strndup(const char *s, size_t n)
Duplicate at most n bytes of a string.
stpcpy
char * stpcpy(char *ZRESTRICT s1, const char *ZRESTRICT s2)
Copy a string and return a pointer to the terminating NUL byte.
strnlen
size_t strnlen(const char *s, size_t maxlen)
Determine the length of a fixed-size string.
strsignal
char * strsignal(int signo)
Return a string describing a signal number.
