UDI_BUF_INSERT(3udi)
Insert bytes into a logical buffer
#include <udi.h>#define \ UDI_BUF_INSERT( \ callback, gcb, new_data, size, \ dst_buf, dst_off) \ udi_buf_write(callback, gcb, new_data, \ size, dst_buf, dst_off, \ 0, UDI_NULL_BUF_PATH)ARGUMENTS callback, gcb are standard arguments described in the "Asynchronous Service Calls" section of "Calling Sequence and Naming Conventions".
new_data is a pointer to the new data bytes to insert into the buffer data. If set to NULL, the size bytes inserted into dst_buf at dst_off shall have unspecified values.
size is the number of bytes to insert into dst_buf.
dst_buf is a handle to the logical buffer into which to insert bytes.
dst_off is the logical offset from the first valid data byte in the buffer to the start of the insertion, in bytes.
DESCRIPTION UDI_BUF_INSERT inserts size bytes into dst_buf at offset dst_off, logically moving any data currently at dst_off "down" by size bytes.
The macro UDI_BUF_INSERT must be called as if it had the following functional interface, as can be derived from the above macro definition and the definition of udi_buf_write:
void UDI_BUF_INSERT ( udi_buf_write_call_t *callback, udi_cb_t *gcb, void *new_data, udi_size_t size, udi_buf_t *dst_buf, udi_size_t dst_off ); typedef void udi_buf_write_call_t ( udi_cb_t *gcb, udi_buf_t *new_dst_buf );
