Defined in header
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 TR,
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
|str1||-||pointer to the null-terminated byte string to duplicate|
A pointer to the newly allocated string, or a null pointer if an error occurred.
The function is identical to the POSIX strdup.
