Since size_t is unsigned on * Windows, functions like read_socket that return -1 on * error cannot return a size_t. * * THIS WAS A MAJOR BUG - it caused frequent, unpredictable * crashes, and also frequently caused JB to jump to 100% * CPU and stay there. (Because it thought it had just * read ((unsigned)-1) == 4Gb of data...) * * - The signature of write_socket has changed, it now simply * returns success=0/failure=nonzero. * * - Trying to get rid of a few warnings --with-debug on * Windows, I've introduced a new type "jb_socket". This is * used for the socket file descriptors. On Windows, this * is SOCKET (a typedef for unsigned). Everywhere else, it's * an int. The error value can't be -1 any more, so it's * now JB_INVALID_SOCKET (which is -1 on UNIX, and in * Windows it maps to the #define INVALID_SOCKET.) * * - The signature of bind_port has changed. * * Revision 1.4 2002/03/07 03:51:36 oes * - Improved handling of failed DNS lookups * - Fixed compiler warnings etc * * Revision 1.3 2001/07/29 19:01:11 jongfoster * Changed _FILENAME_H to FILENAME_H_INCLUDED. * Added forward declarations for needed structures. * * Revision 1.2 2001/06/07 23:06:09 jongfoster * The host parameter to connect_to() is now const. * * Revision 1.1.1.1 2001/05/15 13:58:54 oes * Initial import of version 2.9.3 source tree * * *********************************************************************/ #include "project.h" #ifdef __cplusplus extern "C" { #endif struct client_state; extern jb_socket connect_to(const char *host, int portnum, struct client_state *csp); extern int write_socket(jb_socket fd, const char *buf, size_t n); extern int read_socket(jb_socket fd, char *buf, int n); extern void close_socket(jb_socket fd); extern int bind_port(const char *hostnam, int portnum, jb_socket *pfd); extern int accept_connection(struct client_state * csp, jb_socket fd); extern unsigned long resolve_hostname_to_ip(const char *host); /* Revision control strings from this header and associated .c file */ extern const char jbsockets_rcs[]; extern const char jbsockets_h_rcs[]; #ifdef __cplusplus } /* extern "C" */ #endif #endif /* ndef JBSOCKETS_H_INCLUDED */ /* Local Variables: tab-width: 3 end: */
