Setting positions within files

You can use the following library functions to help you reposition within a regular file:

• fseek()
• fseek_unlocked()
• fseeko()
• fseeko_unlocked()
• ftell()
• ftell_unlocked()
• ftello()
• ftello_unlocked()
• fgetpos()
• fgetpos_unlocked()
• fsetpos()
• fsetpos_unlocked()
• lseek()
• rewind()
• rewind_unlocked()

With large file support enabled for AMODE 31 C/C++ applications, you can use the following library functions for 64-bit offsets:

• fseeko()
• fseeko_unlocked()
• ftello()
• ftello_unlocked()
• lseek()

For AMODE 64 C/C++ applications, large files are automatically supported in the LP64 programming model. All of the above functions (both lists) can be used with 64-bit offsets.
