Format
#include <stdlib.h>
void _makepath(char *path, char *drive, char *dir,
char *fname, char *ext);
Language Level: Extension
_makepath creates a single path name, composed of
a drive letter, directory path, file name, and file name
extension.
The path argument should point to an empty buffer large enough to hold the complete path name. The constant _MAX_PATH, defined in <stdlib.h>, specifies the maximum size allowed for path. The other arguments point to the following buffers containing the path name elements:
| drive | A letter (A, B, ...) corresponding to the desired drive and an optional following colon. _makepath inserts the colon automatically in the composite path name if it is missing. If drive is a null character or an empty string, no drive letter or colon appears in the composite path string. |
| dir | The path of directories, not including the drive designator or the actual file name. The trailing slash is optional, and either slash (/) or backslash (\) or both can be used in a single dir argument. If a trailing slash or backslash is not specified, it is inserted automatically. If dir is a null character or an empty string, no slash is inserted in the composite path string. |
| fname | The base file name without any extensions. |
| ext | The actual file name extension, with or without a leading period. _makepath inserts the period automatically if it does not appear in ext. If ext is a null character or an empty string, no period is inserted in the composite path string. |
The size limits on the above four fields are those specified by the constants _MAX_DRIVE, _MAX_DIR, _MAX_FNAME, and _MAX_EXT, which are defined in <stdlib.h>. The composite path should be no larger than the _MAX_PATH constant also defined in <stdlib.h>; otherwise, the operating system does not handle it correctly.
Note: No checking is done to see if the syntax of the file name is correct.
Return Value
There is no return value.
Example
This example builds a file name path from
the specified components.
#include <stdio.h> #include <stdlib.h>
int main(void)
{
char path_buffer[_MAX_PATH];
char drive[_MAX_DRIVE];
char dir[_MAX_DIR];
char fname[_MAX_FNAME];
char ext[_MAX_EXT];
_makepath(path_buffer, "c", "qc\\bob\\eclibref\\e", "makepath", "c");
printf("Path created with _makepath: %s\n\n", path_buffer);
_splitpath(path_buffer, drive, dir, fname, ext);
printf("Path extracted with _splitpath:\n");
printf("drive: %s\n", drive);
printf("directory: %s\n", dir);
printf("file name: %s\n", fname);
printf("extension: %s\n", ext);
return 0;
