NAME
curl_maprintf, curl_mfprintf, curl_mprintf, curl_msnprintf, curl_msprintf curl_mvaprintf,
curl_mvfprintf, curl_mvprintf, curl_mvsnprintf, curl_mvsprintf - formatted output conver-
sion
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);
DESCRIPTION
These are all functions that produces output according to a format string and given argu-
ments. 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 fprintf() 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 specifies the length of the
target buffer.
curl_mvprintf()
Normal vprintf() clone.
curl_mvfprintf()
Normal vfprintf() clone.
curl_mvsprintf()
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 specifies 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 vari-
able 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.
AVAILABILITY
These function will be removed from the public libcurl API in a near future. They will
instead be made "available" by source code access only, and then as curlx_-prefixed func-
tions. See lib/README.curlx for further details.
RETURN VALUE
The 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.
