curl_maprintf, curl_mfprintf, curl_mprintf, curl_msnprintf, curl_msprintf curl_mvaprintf, curl_mvf- printf, curl_mvprintf, curl_mvsnprintf, curl_mvsprintf - formatted output conversion SYNOPSIS#include <curl/mprintf.h> int curl_mprintf(const char *format, ...); int curl_mfprintf(FILE *fd, const char *format, ...); int curl_msprintf(char *buffer, const char *format, ...); int curl_msnprintf(char *buffer, size_t maxlength, const char *format, ...); int curl_mvprintf(const char *format, va_list args); int curl_mvfprintf(FILE *fd, const char *format, va_list args); int curl_mvsprintf(char *buffer, const char *format, va_list args); int curl_mvsnprintf(char *buffer, size_t maxlength, const char *format, va_list args); char *curl_maprintf(const char *format, ...); char *curl_mvaprintf(const char *format, va_list args); DESCRIPTIONThese are all functions that produces output according to a format string and given arguments. These are mostly clones of the well-known C-style functions and there will be no detailed explanation of all available formatting rules and usage here. See this table for notable exceptions. curl_mprintf() Normal printf() clone. curl_mfprintf() Normal fprinf() clone. curl_msprintf() Normal sprintf() clone. curl_msnprintf() snprintf() clone. Many systems don't have this. It is just like sprintf but with an extra argument after the buffer that speci- fies the length of the target buffer. curl_mvprintf() Normal vprintf() clone. curl_mvfprintf() Normal vfprintf() clone. Normal vsprintf() clone. curl_mvsnprintf() vsnprintf() clone. Many systems don't have this. It is just like vsprintf but with an extra argument after the buffer that speci- fies the length of the target buffer. curl_maprintf() Like printf() but returns the output string as a malloc()ed string. The returned string must be free()ed by the receiver. curl_mvaprintf() Like curl_maprintf() but takes a va_list pointer argument instead of a variable amount of arguments. To easily use all these cloned functions instead of the normal ones, #define _MPRINTF_REPLACE before you include the <curl/mprintf.h> file. Then all the normal names like printf, fprintf, sprintf etc will use the curl-functions instead. RETURN VALUEThe curl_maprintf and curl_mvaprintf functions return a pointer to a newly allocated string, or NULL it it failed. All other functions return the number of character they actually outputed. SEE ALSOprintf(3), sprintf(3), fprintf(3), vprintf(3) Man(1) output converted with man2html |
