strdup, strndup, strdupa, strndupa - duplicate a string
#include <string.h> char *strdup(const char *s); char *strndup(const char *s, size_t n); char *strdupa(const char *s); char *strndupa(const char *s, size_t n);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
The strndup() function is similar, but copies at most
n bytes. If
s is longer than
n bytes are copied, and a terminating null byte ('\0') is added.
On success, the strdup() function returns a pointer to the duplicated string. It returns NULL if insufficient memory was available, with
errno set to indicate the cause of the error.
Insufficient memory available to allocate duplicate string.
