23.9. slapi_ch_realloc()
Description
Changes the size of a block of allocated memory.
Syntax
#include "slapi-plugin.h" char * slapi_ch_realloc( char *block, unsigned long size );
Parameters
This function takes the following parameters:
|
block
| Pointer to an existing block of allocated memory. |
|
size
| New size of the block of memory you want allocated. |
Returns
This function returns a pointer to the reallocated space of memory. If space cannot be allocated, e.g., no more virtual memory exists, the slapd program terminates.
Memory Concerns
This function terminates the slapd server with an "out of memory" error message if memory cannot be allocated.
The block parameter passed to
slapi_ch_realloc() should be the address of a pointer that was allocated using a slapi call such as slapi_ch_malloc(), slapi_ch_calloc(), or slapi_ch_strdup(). The returned pointer should be freed by calling slapi_ch_free().
