strdup

| char * strdup(const char *str1); |
(dynamic memory TR) | |
Returns a pointer to a null-terminated byte string, which is a duplicate of the string pointed to by str1. The returned pointer must be passed to free to avoid a memory leak.
If an error occurs, a null pointer is returned and errno may be set.
As all functions from Dynamic Memory TS, strdup is only guaranteed to be available if __STDC_ALLOC_LIB__ is defined by the implementation and if the user defines __STDC_WANT_LIB_EXT2__ to the integer constant 1 before including string.h.
Parameters
| str1 | - | pointer to the null-terminated byte string to duplicate |
Return value
A pointer to the newly allocated string, or a null pointer if an error occurred.
Notes
The function is identical to the POSIX strdup except that it is allowed, but not required to set errno on error.
