| 51 | .SH DESCRIPTION | |
| 52 | These routines are provided for writing portable software that uses | |
| 53 | .IR libtiff ; | |
| 54 | they hide any memory-management related issues, such as dealing with segmented | |
| 55 | architectures found on 16-bit machines. | |
| 56 | .PP | |
| 57 | .I _TIFFmalloc | |
| 58 | and | |
| 59 | .I _TIFFrealloc | |
| 60 | are used to dynamically allocate and reallocate memory used by | |
| 61 | .IR libtiff ; | |
| 62 | such as memory passed into the I/O routines. Memory allocated through these | |
| 63 | interfaces is released back to the system using the | |
| 64 | .I _TIFFfree | |
| 65 | routine. | |
| 66 | .PP | |
| 67 | Memory allocated through one of the above interfaces can be set to a known | |
| 68 | value using | |
| 69 | .IR _TIFFmemset , | |
| 70 | copied to another memory location using | |
| 71 | .IR _TIFFmemcpy , | |
| 72 | or compared for equality using | |
| 73 | .IR _TIFFmemcmp . | |
| 74 | These routines conform to the equivalent | |
| 75 | .SM ANSI | |
| 76 | C routines: | |
| 77 | .IR memset , | |
| 78 | .IR memcpy , | |
| 79 | and | |
| 80 | .IR memcmp , | |
| 81 | repsectively. | |
| 82 | .SH DIAGNOSTICS | |
| 83 | None. | |
