All libcurl source * files in 'lib' subdirectory as well as those living deep inside * 'packages' subdirectories and linked together in order to build * libcurl library shall follow it. * * File lib/strdup.c is an exception, given that it provides a strdup * clone implementation while using malloc. Extra care needed inside * this one. * * The need for curl_memory.h inclusion is due to libcurl's feature * of allowing library user to provide memory replacement functions, * memory callbacks, at runtime with curl_global_init_mem() * * Any *.c source file used to build libcurl library that does not * include curl_memory.h and uses any memory function of the five * mentioned above will compile without any indication, but it will * trigger weird memory related issues at runtime. * */ #ifndef CURLDEBUG /* * libcurl's 'memory tracking' system defines strdup, malloc, calloc, * realloc and free, along with others, in memdebug.h in a different * way although still using memory callbacks forward declared above. * When using the 'memory tracking' system (CURLDEBUG defined) we do * not define here the five memory functions given that definitions * from memdebug.h are the ones that shall be used. */ #undef strdup #define strdup(ptr) Curl_cstrdup(ptr) #undef malloc #define malloc(size) Curl_cmalloc(size) #undef calloc #define calloc(nbelem,size) Curl_ccalloc(nbelem, size) #undef realloc #define realloc(ptr,size) Curl_crealloc(ptr, size) #undef free #define free(ptr) Curl_cfree(ptr) #ifdef _WIN32 #undef _tcsdup #ifdef UNICODE #define _tcsdup(ptr) Curl_wcsdup(ptr) #else #define _tcsdup(ptr) Curl_cstrdup(ptr) #endif #endif /* _WIN32 */ #endif /* CURLDEBUG */ #endif /* HEADER_CURL_MEMORY_H */
