| 38 | .Sh NAME | ||
| 39 | .Nm realloc | ||
| 40 | .Nd reallocation of memory function | ||
| 41 | .Sh SYNOPSIS | ||
| 42 | .Fd #include <stdlib.h> | ||
| 43 | .Ft void * | ||
| 44 | .Fn realloc "void *ptr" "size_t size" | ||
| 45 | .Sh DESCRIPTION | ||
| 46 | The | ||
| 47 | .Fn realloc | ||
| 48 | function changes the size of the object pointed to by | ||
| 49 | .Fa ptr | ||
| 50 | to the size specified by | ||
| 51 | .Fa size . | ||
| 52 | The contents of the object are unchanged up to the lesser | ||
| 53 | of the new and old sizes. | ||
| 54 | If the new size is larger, the value of the newly allocated portion | ||
| 55 | of the object is indeterminate. | ||
| 56 | If | ||
| 57 | .Fa ptr | ||
| 58 | is a null pointer, the | ||
| 59 | .Fn realloc | ||
| 60 | function behaves like the | ||
| 61 | .Xr malloc 3 | ||
| 62 | function for the specified size. | ||
| 63 | Otherwise, if | ||
| 64 | .Fa ptr | ||
| 65 | does not match a pointer earlier returned by the | ||
| 66 | .Xr calloc 3 , | ||
| 67 | .Xr malloc 3 , | ||
| 68 | or | ||
| 69 | .Fn realloc | ||
| 70 | function, or if the space has been deallocated | ||
| 71 | by a call to the | ||
| 72 | .Xr free | ||
| 73 | or | ||
| 74 | .Fn realloc | ||
| 75 | function, unpredictable and usually detrimental | ||
| 76 | behavior will occur. | ||
| 77 | If the space cannot be allocated, the object | ||
| 78 | pointed to by | ||
| 79 | .Fa ptr | ||
| 80 | is unchanged. | ||
| 81 | If | ||
| 82 | .Fa size | ||
| 83 | is zero and | ||
| 84 | .Fa ptr | ||
| 85 | is not a null pointer, the object it points to is freed. | ||
| 86 | .Pp | ||
| 87 | The | ||
| 88 | .Fn realloc | ||
| 89 | function returns either a null pointer or a pointer | ||
| 90 | to the possibly moved allocated space. | ||

| 96 | .Sh STANDARDS | ||
| 97 | The | ||
| 98 | .Fn realloc | ||
| 99 | function conforms to | ||
