The %realloc() function resizes the memory buffer specified to the specified size in bytes and returns a pointer to the resized buffer. The contents of the buffer are not changed. If buffer is null, this function behaves like the %malloc() function for the specified size. If the specified size is zero and the specified buffer is not null, the buffer memory is freed.
var = (char*)%realloc((char*)buffer, size)
| buffer | Buffer to resize. | |
| size | Number of bytes to reallocate to the specified buffer. | |
