slapi_ch_realloc()

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 (in bytes) 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 (for example, if no more virtual memory exists), the slapd program terminates.

Memory Concerns

This function should be called instead of the standard realloc() C function, and terminates the slapd server with an “out of memory” error message if memory cannot be allocated.

The block parameter passed to this function 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() .
