The alloca() function is machine- and compiler-dependent. For certain applications, its use can improve efficiency compared to the use of malloc(3) plus free(3). In certain cases, it can also simplify memory deallocation in applications that use longjmp(3) or siglongjmp(3). Otherwise, its use is discouraged. Web(3) allocate and free dynamic memory Other Alias free, calloc, realloc SYNOPSIS #include void *malloc (size_t size); void free (void *ptr); void *calloc (size_t nmemb, size_t size); void *realloc (void *ptr, size_t size); DESCRIPTION The malloc () function allocates size bytes and returns a pointer to the allocated memory. Webstrdupa() and strndupa() are similar, but use alloca(3) to allocate the buffer. They are available only when using the GNU GCC suite, and suffer from the same limitations … ford wire repair kit
