3.192 strdup

Function

Allocate a copy of a string on the heap.

Header

string.h

Declaration

char* __fastcall__ strdup (const char* s);

Description

strdup allocates a memory block on the heap, big enough to hold a copy of s including the terminating zero. If the allocation fails, NULL is returned, otherwise s is copied into the allocated memory block, and a pointer to the block is returned.

Limits

• The function is only available as fastcall function, so it may only be used in presence of a prototype.
• It is up to the caller to free the allocated memory block.

Availability
