dstring_t 3 dstring_t data structure for dynamic string representation #include <cds/dstring.h> typedef struct _dstring_t { dlink_t buffers; int len; int buff_size; } dstring_t; This structure represents dynamic string. It allows concatenation of multiple strings without worry about memory allocations. Internaly it uses list of data buffers which are allocated if needed. The content of dynamic string may be copied out from internal buffers using simple function call (see ). Internal buffers are allocated in package memory (when compiled with SER)! This structure is used as base for simple object serialization (see ). buffers linked list of allocated data buffers len whole string length buff_size size of newly allocated buffers Warning - structure internals may change! For manipulation use manipulation functions. #include <cds/dstring.h> #include <cds/sstr.h> int main(int argc, char **argv) { dstring_t str; str_t s; dstr_init(&str, 256); dstr_append_zt(&str,"This is a "); dstr_append_zt(&str,"very long "); dstr_append_zt(&str,"string."); if (dstr_get_str(&str, &s) == 0) { printf("result: %.*s\n", FMT_STR(s)); str_free_content(&s); } dstr_destroy(&str); return 0; } This will result in result: This is a very long string. Create a function like sprintf. , , ,
