| | 50 | .SH DESCRIPTION |
| | 51 | These routines are provided for writing portable software that uses |
| | 52 | .IR libtiff ; |
| | 53 | they hide any memory-management related issues, such as dealing with segmented |
| | 54 | architectures found on 16-bit machines. |
| | 55 | .PP |
| | 56 | .I _TIFFmalloc |
| | 57 | and |
| | 58 | .I _TIFFrealloc |
| | 59 | are used to dynamically allocate and reallocate memory used by |
| | 60 | .IR libtiff ; |
| | 61 | such as memory passed into the I/O routines. Memory allocated through these |
| | 62 | interfaces is released back to the system using the |
| | 63 | .I _TIFFfree |
| | 64 | routine. |
| | 65 | .PP |
| | 66 | Memory allocated through one of the above interfaces can be set to a known |
| | 67 | value using |
| | 68 | .IR _TIFFmemset , |
| | 69 | copied to another memory location using |
| | 70 | .IR _TIFFmemcpy , |
| | 71 | or compared for equality using |
| | 72 | .IR _TIFFmemcmp . |
| | 73 | These routines conform to the equivalent |
| | 74 | .SM ANSI |
| | 75 | C routines: |
| | 76 | .IR memset , |
| | 77 | .IR memcpy , |
| | 78 | and |
| | 79 | .IR memcmp , |
| | 80 | repsectively. |
| | 81 | .SH DIAGNOSTICS |
| | 82 | None. |
