Changes the size of a block of allocated memory.
#include "slapi-plugin.h" char * slapi_ch_realloc( char *block, unsigned long size );
This function takes the following parameters:
Pointer to an existing block of allocated memory.
New size (in bytes) of the block of memory you want allocated.
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.
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 returned pointer should be freed by calling slapi_ch_free() .
