| 23 .SH NAME | |
| 24 curl_global_init_mem - Global libcurl initialisation with memory callbacks | |
| 25 .SH SYNOPSIS | |
| 26 .B #include <curl/curl.h> | |
| 27 .nf | |
| 28 .B "CURLcode curl_global_init_mem(long " flags, | |
| 29 .B " curl_malloc_callback "m, | |
| 30 .B " curl_free_callback "f, | |
| 31 .B " curl_realloc_callback "r, | |
| 32 .B " curl_strdup_callback "s, | |
| 33 .B " curl_calloc_callback "c ");" | |
| 34 .SH DESCRIPTION | |
| 35 This function works exactly as \fIcurl_global_init(3)\fP with one addition: it | |
| 36 allows the application to set callbacks to replace the otherwise used internal | |
| 37 memory functions. | |
| 38 | |
| 39 If you are using libcurl from multiple threads or libcurl was built with the | |
| 40 threaded resolver option then the callback functions must be thread safe. The | |
| 41 threaded resolver is a common build option to enable (and in some cases the | |
| 42 default) so we strongly urge you to make your callback functions thread safe. | |
| 43 | |
| 44 All callback arguments must be set to valid function pointers. The | |
| 45 prototypes for the given callbacks must match these: | |
| 46 .IP "void *malloc_callback(size_t size);" | |
| 47 To replace malloc() | |
| 48 .IP "void free_callback(void *ptr);" | |
| 49 To replace free() | |
| 50 .IP "void *realloc_callback(void *ptr, size_t size);" | |
| 51 To replace realloc() | |
| 52 .IP "char *strdup_callback(const char *str);" | |
| 53 To replace strdup() | |
| 54 .IP "void *calloc_callback(size_t nmemb, size_t size);" | |
| 55 To replace calloc() | |
| 56 .RE | |
| 57 This function is otherwise the same as \fIcurl_global_init(3)\fP, please refer | |
| 58 to that man page for documentation. | |
| 59 .SH "CAUTION" | |
| 60 Manipulating these gives considerable powers to the application to severely | |
| 61 screw things up for libcurl. Take care! | |
